For anyone who has ever been to a NASCAR Race. The specter of a fatal crash is always there. We saw a number of bad crashes at Charlotte. Miraculously Richard Petty survived
Darlington was a very difficult track to race cleanly on. All four corners were different curvatures and the banking was different throughout the track. Oh, and for added fun, the straights were different lengths. Even getting into and out of the pits wasn't easy.
