Never did the motorbike thing. My father wore out several of them as a courier during WWII. I guess he might have wrecked a few as well. At any rate, he would not let me have one while I lived under "his" roof. Guess he figured out how risky they were.
When I started university, the older couple who let me stay with them were antique nuts. The fellow did regular road trips to Yukon and Alaska looking for abandoned elderly wrecks. If he found one, he would track down the owner and offer to dig it out of the weeds and take it home on his cargo trailer. He always came back with a new project or two. Which brings me back to bikes. He gave me a complete Indian motorcycle in a few boxes and suggested that it might be fun for me to rebuild it. He was right, it would be worth a pretty penny now. However school sucked me dry, so it never got very far out of the boxes. OTOH, had I finished it, I am not sure I would have survived the learning curve by starting with that one.
