There are plenty of endurance races available to anyone who wants to race $500 junkyard relics. There are also some endurance races available to drivers who want to race million dollar prototypes. But the options are pretty limited for those who want to race something in between.
I began driving race cars in 1985. In the thirty years since, I've had a total of one (1) serious neck injury while racing. It was at Plymouth Speedway in the summer of 1995. I have not had another neck injury since.
