Ron and Dusty:
Ran trials in the mid-late '60's. Ended up with a John Penton 6-day Custom, and ran some of those trials, too, getting up into the international classes. THAT'S when I ran against the Europeans and discovered what eternal pain really is.....6 days of punishment on a motorcycle, and they seemed to thrive on it.
I rode my last race in August, 1969, in Louden, NH (when it was still a decent motorcycle event) and finished 21'st out of 68 after six days (18 dropped out), went home, sold my bikes and never looked back. Later, after the four accidents with my bicycle (none of which were remotely my fault) I really cannot ride a bike for anything more than an hour or two without pain, so I have a nice, cushy seat in the Speedster and truck with lots of neck support and that's fine with me.
Funny, though....without a lot of encouragement from me, my son became a biker, too; first with moto-cross types of bikes, and now with a Honda CBR800 (forgive me if I got that model wrong) which he loves.
As they say, the apple doesn't fall far........
STAN! My first bike was a Zundapp 125!!!!!! Not exactly an off-road kind of bike, but a good starter none-the-less (until you tried to get parts for it). A couple of my friends ran Jawas in scramble events. You could always tell when they went by - they had this strange, low, 4-stroke exhaust note that was very distinctive.....
