Tourism in Denali National Park, home to 20,320-foot Mount McKinley, could get a lot greener before we know it.

If you've been to Denali you know that the park forbids personal cars for the 92-mile length of the park road. Instead, visitors catch a diesel bus near the park entrance. The road is the only way to get into and out of the park.

Park officials are now testing out a hybrid tour bus to eventually replace the fleet of 110 diesel buses that take thousands each year to view North America's highest mountain and the wildlife that surrounds it.

Officials tell the Associated Press that these hybrids reduce the amount carbon dioxide emissions by 40 percent, nitrogen oxide emissions by another 20 percent and particulate emissions by 30 percent.

That translates into a much more environmentally friendly vehicle for one of the country's most beautiful...environments.

Officials are also touting the gas efficiency of the hybrids, since diesel fuel in the area is topping out at around $5 a gallon. The hybrid bus requires around 70 percent less fuel as the park's current diesel buses.

The hybrid system combines a diesel engine with an 80-kilowatt powertrain that incorporates a transmission, batteries and an electric motor, the AP reports.

Right now the park is looking to slowly phase out its diesel fleet, and officials tell the AP it could replace anywhere from two to 12 buses each year with the hybrid models.

But this will come with a significant price tag: Each hybrid bus costs $200,000 -- twice as much as the buses currently in use.

You can't visit Central America and not make at least some effort to see the monkeys. That's just wrong. Monkeys are way too cute to be missed.

Like Costa Rica, and other countries in this region, Belize is also trying to brand itself as an ecotourism destination.

The Community Baboon Sanctuary, a conservation project in which over 200 private landowners in Belize have voluntarily pledged to conserve their land for the protection of the Black Howler Monkey (called 'baboon' in the local Creole dialect) habitat, is well-worth the trip inland. It's only about an hour drive from Belize City.

But, there is a but.

Mosquitoes. Mosquitoes. Mosquitoes.
Before I begin talking about how cute the monkeys are, I am going to say this: I had never, ever before, seen so many mosquitoes before visiting the Community Baboon Sanctuary (CBS). Anywhere.

The closest I had ever come to this kind of mosquito infestation was in Venice. (Camping outside a city built on a swamp is not a good idea, note to self.)

Just opened in Pentonville Road, Islington (Greater London) is Surya (Hindi for "Sun" and Sanskrit for "Sun God"), the world's first green nightclub.

It will generate its own electricity when people move on its floors, will operate on solar and wind energy, has air-flush waterless urinals and low-flush toilets, and free entry for cyclists and walkers. Otherwise club entry is £10 and customers must sign a pledge towards helping combat climate change.

Brainchild of Mr.Charalambous, head of Club4Climate, the club's dance floor is made of crystal and ceramic, which when trodden on generates electricity under the concept of "piezoelectricity". This current is fed into nearby batteries, which in turn fuel the club. It is estimated that if a large group of clubbers danced vigorously, they could generate 60% of the club's energy needs.

With aim of inspiring the youth to get involved in tackling the issue of global warming, Charalambous said in the Times of India: "Unless we stop preaching to people and use an inclusive philosophy we're never going to create the revolution to combat climate change." I couldn't agree more.

Hello from Belize! What a beautiful little country this is.

I have wanted to come here forever, being a diver and all. As you probably know, the Belize Barrier Reef (stretching from Yucatan all the way to the coast of Guatemala) is the second largest reef in the world, after the Great Barrier Reef.

We took our first dive trip today, right off the Ambergris Caye island. It was just a shallow dive with a bunch of snorkelers who desperately wanted to "see some sharks." This part of the reef is know for its abundance of nurse sharks, pretty harmless types of sharks who eat by suction (hence the name). Still, they are sharks, aka beautiful creatures.

The dive instructor threw in some bait (an enormous fish head) and a few minutes later, a bunch of sharks (I saw five, the largest at least two meters long) and sting rays (the largest was over a meter across) came by for the feast. It was an incredible sight.

I don't know how I feel about the whole "petting the shark and sting ray" aspect of the whole thing. The instructors caught a couple of the sharks by the fin and let everyone in the group touch them. Same with the sting rays. I felt a little bad for them. I can't be good for them to have a hundred people a day touch them, right?

Even if you manage to do more than a staycation this summer, vacations just aren't what they used to be. Along with paying to check baggage and incredibly high gas prices comes a whole new level of social responsibility; seems like we can't even take a simple American road trip without considering all the environmental costs involved.

For those of you that are concerned with just how green your summer travels are, the Sierra Club has two easy quizzes to figure out where your vacation ranks on the green scale. The How Green is My Destination quiz looks at the environmental impact of where you are going and the How Green is my Getaway quiz analyzes just how your mode of travel -- bike, bus, airplane, etc. -- changes the greeness of your upcoming vacay.

The only time my family on either side of my tree has had a reunion was when my dad's side converged at Fontana Village near Fontana Dam for a week. In the midst of the Great Smoky Mountains, this was a gorgeous place to spend time.

The drive there was filled with winding roads and vistas. Next year marks the 75th anniversary of Great Smoky Mountains National Park. Seventy-five years ago, from donations collected from the public and private sectors, the land in North Carolina and Tennessee that now boasts 800 miles of maintained trails, 1,500 black bears, plus elk and deer, became property for the public to enjoy.

If you can't make it to the anniversary celebration, there are planned activities throughout the spring, summer and fall every year. This summer is filled with them. Here's the link to the interactive calendar that highlights what is happening on specific days. I adore ranger programs. I've never seen a bad one.

To kick off the 75th anniversary, there is a nifty Web site that highlights the upcoming activities and the park history. The interactive timeline that dates back to pre-1900s is particularly cool. For example, did you know that Clarence Darrow visited here in 1925 when he was in the midst of the Scopes "Monkey" Trial?

Along with the park itself, the neighboring communities also have events planned to celebrate the beauty in their midst. Knoxville, Tennessee has several. From what I can tell, events will be added as the year goes on, so keep checking back.

If you have been to the Great Smoky National Park and want to add to the legacy, there's a feature, "Smokies Family Album" where you can share your photos.

The big weekend Anniversary Weekend is June 13-15. 2009.

Two summers ago my son was wild about cicadas. They were everywhere, and each time he found one of their shells he put it in an empty bottle. His exuberance was the type only four-year-olds can generate

There's a museum in New Orleans with his name on it. Not literally, the museum is called Audubon Insectarium, but it's the kind he would LOVE. This museum is the first new tourist attraction to open since Katrina changed the landscape of much of the city and is part of Audubon Nature Institute. I found out about it through this article in the Columbus Dispatch.

The landscape inside the Audubon Insectarium is bugs, bugs and more bugs--35,000 live ones and 15,000 mounted ones--or thereabouts. As people go from exhibit to exhibit, they learn about bugs from prehistoric times through today.

Built in the historic U.S. Custom House, the museum offers entertainment and creativity in how it displays its subject matter. For example, you can get an idea of what a bug's world looks like through reconstructed tunnels that puts you in the bug's perspective. Outside the bathrooms, you can see dung beetles roll waste into balls. In case you're wondering-it's not the waste from the bathroom. There's also a chance to test your mettle against a cricket's power. Can you pedal as fast as a cricket can hop?

Another exhibit is devoted to showing what insects people eat around the world and how they are cooked. That sounds like an exhibit Andrew Zimmern of Bizarre Foods would swoon over. If you want to try an insect yourself, you can try some edible bug snacks. I've had chocolate covered grasshoppers before. The closest thing I can think of is Nestle Crunch bars.

Also, there is a section about pest control management and a live butterfly exhibit among other offerings.

Lest you think getting rid of all insects but the pretty kind, one of the main points the museum makes is that if it weren't for bugs, nothing else would live. Remember the lyrics to the song, "There was an Old Woman Who Swallowed a Fly?" It's kind of like that.

There's Breakfast with the Bugs on July 12. Notice it's with the bugs, not eating bugs.

Your house is definitely not the coolest on the block unless its made out of jumbo jet pieces. Francie Rehwald, daughter to a family owning multiple Mercedes Benz dealerships across California, just started construction on her new house made completely out of fragments of a scrapped Boeing 747. For forty thousand dollars, Rehwald purchased the pieces from an airplane junk yard in the Mojave Desert and after waiting over a year to get 17 permits pushed through the bureaucracy, finally just started taking delivery of wing segments.

The house and various surrounding structures will be built out of every single piece of the aircraft. In addition to the main 4000 foot square homestead, pieces like the nosecone will be used for a meditation pagoda while the tail will be used as a viewing platform for the surrounding area.

Rehwald, who says "I love to recycle, I love green houses and contemporary architecture, and I especially love nature and the natural environment," apparently believes that this structure will be a sustainable, green alternative to conventional construction.

What's interesting to me is that Rehwald still considers herself a staunch environmentalist in spite of the ruckus and cost involved. Sure, she's recycling old materials to use for her home, but do the economic and environmental impact of moving the parts up to LA justify it? A helicopter costing $10,000/hour was required to move large sections of the wing, while several sections of the expressway had to be closed to move other parts up the coast. Would is just be better two melt down the aluminum and recycle it? It seems kind of selfish to me.

Heading south, I passed the town of Orikum and the road soon climbed steeply into the Llogara Pass, one of those places that makes you feel very small and alone.

The road clung to a mountainside so steep that when I craned my neck up I couldn't see it top out. On my left there was a verdant valley far below and another huge wall of gray rock. The valley seemed to pinch farther up ahead, for the views were long enough that I could mark the road's progress as it snaked in and out of sharp bends.

Then, rounding one, I confronted the most dramatic and lovely stretch of road I'd seen on the Adriatic/Ionian coast: In the windshield, a ridge line the color of ash loomed over the road and it descended in a tumbling pitch perhaps 2,000 feet into iris blue water. The narrow road worked its way down the green hillside not in gentle curves but in hairpin switchbacks, like an extended mark of Zoro.

Far below, the town of Dhermi perched in resistance, some how, to the Llogara Pass' plunge to the sea.

A few days later, taking a road out of the southern city of Saranda that soon turned into one of the best in Albania -- despite having been marked in yellow on my map, signifying a track slightly better than cracked concrete -- I was again to pull neck muscles trying to take in the immensity of a light-speckled valley that stretched almost to the hill town of Gjirokaster.

In one frame, a single house sat sentry over groves and green terraces, with the patchwork valley floor running away from it in the distance.

These were scenes that revealed how much Albania, despite all its problems, had that was worth protecting.

Gas prices aren't the only expense of a vacation that pinch the finances. Admission fees can be a real downer. If one is traveling with young children, huge, expensive museums can be overwhelming.

These are two reasons why the National Aquarium in Washington, D.C. sounds appealing to me.

At $5 for adults, and $2.50 for children, the admission is not even close to the $18.75 amount for adults to the Newport Aquarium in Newport, Kentucky. The Newport Aquarium, the last one I visited, is quite impressive, but sometimes I'd rather opt for a simpler venue for less money.

Last year, when we went to the Smithsonian National Museum of Natural History, much of our time was spent finding a bathroom and each other. Due to time constraints, we hurried through sections where I wanted to linger. When mixing children with large museums, it's often necessary to leave out entire exhibits in order to not have a kid meltdown halfway through.

With a smaller museum, like the National Aquarium that claims you can see the whole thing in 45 minutes, you don't have to pick and chose among options. At the end of an hour you can end up at the gift shop satisfied and have time and energy left to take in something else close by. I'd head to the outdoor sculpture garden at the National Gallery of Art for starters.

Along with the aquarium's renovations that include new signage, carpeting and exhibits is a new theme--"America's Aquatic Treasures." Look for alligators, eels, sea horses, a baby loggerhead turtle and more. [see Washington Post article]

If you can make here on August 9, it's Shark Day. There are several activities geared towards kids and talks adults would enjoy.
