It took me about 10 years, but I found one of every bike I grew up riding. Some of them were fairly nice, but most of them did not run and were piles of junk. I overhauled the engines and restored many of them from the frame up! It was a great activity and if you're one of those guys that says, "I sure wish I had my old bike from when I was a kid!" , my advice for you is to go find one (or more)! This has been a VERY fun project and I'm pretty good at turning a wrench and painting now!
