My dad worked with a guy name Jim Howell years ago. It seems Jim and John Buttera grew-up together and were both into customizing bicycles at a very young age (I think he said around 9 years old). Jim was the guy who designed hemi underglass and the lil red wagon. Jim's brother actually built the cars. As far as I know Jim still builds custom bicycles under the name Crawford cycles. Two true innovators that started out working on bicycles. He will be missed......
