While I'm up at school, I ride almost exclusively. I'm not into the whole green, eco-friendly movement--just not my thing. However, living in a town that's flat as a pancake and only 10 miles wide or so, it's just more practical to bike everywhere.
I bike to escape from the stresses of daily life. When I'm in the saddle, I don't really care about anything except the ride. I often make up excuses to go on rides instead of doing homework or studying, but the exercise helps me focus when I get back.
Basically, I love to ride just for the sake of riding. The fashion of it becomes irrelevant as long as I'm enjoying myself.
