I agree with you, Cal, I love to bike also.

I ride a 27" mountain bike though, but it has street tires. I'm not into competitive biking or long distance, I just use it run small errands (low gas mileage and zero emission) or to go to beach and take a dive. But I have to admit, it does me good to do those aerobics. My body says thank you after every ride. Sedentary as I am it is indeed about the best I can do for myself to keep me physically and mentally fit. Love the shower of endorphins and other brain chemicals that engulf me after every ride. I can recommend it to anyone.

Swimming and body surfing in the Ocean is nice but combined with the deep oxygen intake when doing a ride up and down our SoCal hills is the max. I just turned 50 Thursday (going on 30) and do feel the need for that sustained effort to keep fit.

Keep on biking!
