There are many reasons I cycle and all of them are important. The fact that it's so much fun is definitely one of the most important. When I'm flying along, feeling like a Tour de France rider (okay, it's silly, especially at my age, but I'll bet other people do it too) I'm having so much fun! I always imagine that if I could get other people to try it and find out how much fun it is, they'd become bike nuts too.
