Rod: Thanks for the comment. I hope to be able to have a long time of fun (man that was really bad grammar) and as long as I can restrain myself to not try too much, too soon, it'll all be good. My father used to tell me during my break away from racing, that when I got back into it I should do well, since I would be hungry to win again.
Sorry to hear your about your back...what street bikes do you ride?
Actually, I wasn't very good at mx either, but I did have fun and the other riders found me highly entertaining.
