I've always loved vintage and classic bikes. Hope to own a few more some day. I had a pretty rare 74 BMW R90/S and a 71 CZ 250 that I restored for vintage motorcross. Had a blast racing but most of the time beat the crap out of myself on Sundays just in time for work on Monday. Even had an ambulance haul me away after a crash one time. Kept going for awhile but eventually gave it up. I'd still like to try vintage road racing some day.
Check out my brothers blog. After 40 on 2, he has some interesting bike musings to read through.
