Thanks ladies,
I guess I want a rode bike to get in shape, I have a hybrid, but I think of a hybrid of just cruising around the neigborhood. I think of a rode bike as a 'real training bike'. I also have a permanent knee problem and know that riding is good exercise. Plus I figure if I spend a considerable amount of $$$ I will feel I will have to ride. I will start checking my LBS. I'm the the type that has to extensive research on my purchases. I appreciate all your help. I've owned 2 Treks and a Fuji bike. Sounds like alot of you own Treks, Jamis and Giant bikes.
