Thanks everyone! I'm really excited about riding more.

Jennifer - where did you go for your bike? There's a shop in Rome, and one on the south side of Chattanooga in Ringgold, and those are the only 2 I know. Bob's in Rome didn't have much last time I was there (3 road bikes!) but the one in Ringgold has lots they need to get rid of - apparently the owners have a friend with another store, the owner of the other store had a bad accident and the owners of this store bought his inventory to help him out.
