in 7th grade, on my way to school, with my books stuffed in my shirt, I popped a wheelie on my stingray and my front wheel flew off, I cam down hard but survived, I watched the wheel roll really really far down the avenue and even crossed it and kept going, this is after I got up from the fall, that thing went on forever. I don't remember the rest but I guess I had to walk to the lost wheel, etc. then finger tight the wheel for the rest of the ride. what a way to start my day! lets see, that's probably 1971 or there-a-bouts ...
