Isn't it great that one of the most eco-friendly ways to get around is also one of the most kid-friendly? I can still remember the freedom and exhilaration I felt when riding a bike as a kid. So its no wonder that last summer's surging gas prices sent a lot adults back to their bikes ... not just for fun and exercise, but as a primary means of transportation.

Don't have a bike of your own? Don't despair. Bike-sharing programs are on the rise all across North America, fueled in large part by younger environmentalists who can see "outside the box" when it comes to transportation. According to the International Bicycle Fund, there already are at least 128 programs for bike sharing in 37 of the U.S. states, as well as another 15 or more programs in five provinces in Canada.

To find out if there is one near you, check out the IBF's Community Bike Directory or The Bike Sharing Blog.
