We here in San Francisco always groan a little when visitors rent a car. After all, Fog City is one of the few destinations in the U.S. where it's not necessary to have a car to see the sights. Why pay all that money just to leave the rental in the hotel's parking garage?

Often in the U.S. when we think about "car-free destinations," we think of big cities like New York City, Boston, and San Francisco. But what should you do if you want to go car-free and get away from the hubbub of urban life? I now have an answer for you: visit Santa Barbara.

Editor's Note: It's Earth Week on the blog! In honor of the 40th Anniversary of Earth Day, The Window Seat editors are blogging about our favorite ways to go green while globetrotting. Ask us your eco-questions, join in the green conversation, and help us celebrate Mother Earth.

According to a study by Cars.com, drivers across the country are making the choice go green when they're on the road. The consumer advice site named the top cities for hybrid car shoppers, with San Francisco taking the number one spot. As an Earth-loving traveler, I always encourage other road warriors to think green not just when they're at home, but when they're traveling, too, and the growing number of eco-friendly car rental options makes that challenge easier.

I don't play chess. You could call me uncultured, but I probably wouldn't hear you. I'd be too busy stabbing at a flashing, beeping, handheld touch-screen trying to save the president from exploding skeletons. And let's be honest--most of your fellow airline passengers will be doing the same this season.

But what if you don't have the latest Megafastatron3000 gaming system in hand when you step into the airport? Are you doomed to manipulate magnetic rooks across a tiny chess board? Are you stuck shoving backgammon stones down endless rows of triangles? Nope! Because I'm about to lay down the travel game suggestions, 2009-style.

If you read this blog, you're probably a lot like us, constantly planning your next trip, collecting passport stamps like medals of honor, and always looking for that next peak to climb. The older I get the more keenly I feel that if I love travel this much, I also have a responsibility to preserve beloved destinations for my children and my children's children.

Responsible or green travel is at heart a conservation movement, a desire to keep pristine places around the world as they are--or even restore them to how they were. Here are 10 green travel resolutions you can make for Mother Earth. I've listed them from simplest to most ambitious so you can choose where you'd like to start. If we all make a pact to do just one of these resolutions, I think you'd be surprised at the huge impact it would have over time.

Even if budgets are a little snug this year, travel hopes remain high. Here's a list of affordable travel gifts for the globetrotter on your list. The best part? All of the items are $60 or less (and in many cases, much, much less). Happy holiday shopping!

I'm all about getting sporty on my trips. When I was training for the NYC marathon, I had to visit Washington, D.C. at a crucial point of my training. Instead of halting training or spending hours running on the hotel treadmill, I hired a running guide through City Running Tours who took me on a sightseeing run through our nation's capital.

So when I heard about a physical fitness event  -- again, in Washington, DC -- coming up on October 11, I thought I would share it with you. Bike for the Heart is a day-long event put on by the Sister to Sister organization, a group dedicated to educating women about heart health and risk prevention and providing free heart health checkups.

The day consists of four events:

 - a family-friendly five-mile bike ride around our nation's capital (this would be my choice)

Here’s a secret: the two main reasons I spent a college semester in Paris were nine years of French lessons and National Lampoon’s European Vacation. I saw it when I was very young and could not wait to explore Europe…by car, of course.

In a classic case of careful-what-you-wish-for, that first spring-break road trip—through Germany, Austria, and the Czech Republic—was indeed decidedly Griswoldesque.

But I’ve rented cars in Europe since then, and each trip goes more smoothly than the last. So as I prepare for another European road trip next week and ponder past hits and misses, I’ve come up with my top five tips for seeing Europe through the windshield. If you follow these guidelines, I'm confident you'll discover the joys of renting a car abroad.

When I scheduled my 28-hour stopover in Helsinki, I thought I’d do a whirlwind tour of the city, snapping some quality architecture shots in true shutterbug fashion and doing little else. Au contraire, naïve one. Instead, I spent the majority of my time in Finland getting acquainted with the downtown poliisi precinct.

On my way to the ferry station to purchase my ticket to Estonia, I was crossing at the green crosswalk like the law-abiding citizen I am. Out of nowhere, a minivan cab came whipping around the way, and performed an illegal U-turn—at a red light at that—before I had time to contemplate my next move.

Last week in an unprecedented move, the House narrowly approved an energy bill that would limit harmful greenhouse gases--the first time any chamber of Congress has ever approved limits of this kind. Now the energy bill faces a tough battle in the Senate and already there is vocal opposition from many different camps.

Without access to Capitol Hill, I settled for the next best thing: taking straw polls at happy hour. I asked one simple question: If the climate bill passes, would you be more likely to offset your travels?

Today I'm stopping by The View from the Bay to do a round-up of the best summer travel gadgets. Savvy Window Seat readers already know about a few of the gizmos I'm going to talk about, but here are my top five (in no particular order):
