p.s.- you guys rule... around my town there are a lot of older bikers who really despise the younger generation of bikers for getting into it.. i bike because 1) i love it, it's fun 2) it's way better for the environment, and 3) it's way better for my body... along with a many other more marginal reasons... but the fact of the matter is, these older biking purists don't care about any sort of cause, they just see themselves as an elite group, which i think is complete garbage. needless to say, i have a very provincial (but excellent) group of biking friends with which i can discuss all of these topics, and naturally they don't all have first hand advice.. i guess all i'm saying is, thanks a lot for not being a bunch of old biking codgers. :-D
