When I was a kid, I read a book that was part of a series called, "The Great Brain" or something like that. The series centered around a kid growing up in Utah in the late 1800's. The reason I mention it was because in one chapter, he built a roller coaster from the top of his barn and charged kids a penny to ride. He made all kinds of money, but lost it all when the coaster flew off the track and broke a kid's legs. These were the days before upstop wheels of course. I guess the brain didn't have insurance.
