me3 chiming in on the hybrid. If you decide to go with a road bike I would say go with the cheaper one for now in case you decide you don't really wanna be a biker or you need the money for school etc etc. Coz I can just about promise you - even if you go with the more expensive model, it won't be good enough for you down the road - you'll want an even MORE expensive model! LOL
I'm voting for the hybrid coz it is faster than a Wal-Mart special, it'll keep up with your friends, and it'll take a beating if it has too. I rode over 1000 miles on my "comfort" bike before I got a vintage road bike. I'm still thinking about using the comfort bike for my winter commuter - which brings up another point. If you're planning on riding through the winters - they can be pretty nasty in OK yes??......and the skinnier tires and the harrier handling of a road bike on slick roads could be scary. whereas the hybrid has slightly wider tires and the handling isn't so harrier fast.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
