So, I was watching "The Quest" (1986), with Henry Thomas, which I haven't watched in years. In the beginning, he has outfitted a Schwinn Cruiser 5 to ride on railroad rails. The other children seem pretty ecstatic about his endeavor to reach higher speeds. Was this an actual phenomenon which I missed? I am in the age bracket for this movie, which I used to watch as a kid. I don't remember anyone really outfitting bikes for this, though we used to try to ride on the rails for as long as possible, more as a balancing act. Does anyone know if this was a popular activity, or merely something to lend to the feel of the film, and the ingenuity and creativity of the main character? Thanks
