I like the exersise and the alone time when I bike... I hate that my office is 22 miles from my house. Especially on the way home. That combined with the hours I work and the fact that I spend most of my work day outside make it impractical for every day, as I just don't have that kind of energy. Also right now with the winter weather I hate getting ready for the ride, it feels like I moved out west with less **** than I need to pedal across town.
