Jeff Mapes said it best in his book Pedaling Revolution, "The bike offers a non-polluting, non-congesting, physically active form of transportation in a country, and in a world, that increasingly seems to need such options.... Our increasingly sedentary lifestyle raises the specter of an obesity epidemic that could shorten the life span of the next generation."
People for bikes is a great site dedicated to getting more people on bikes. I highly suggest signing the pledge and getting involved with them. This picture I got off their site gives great reasons to ride a bike and great reasons to get your friends to join you.
