It's amazing where racecars can end up; I don't think anyone ever dreamed you could hang a Sprint Car by its' cage from the top of a catch fence pole at Ascot but Clark Templeman proved that you could, with tragic results. Not long after that every pole in the place had a tire on top of it to prevent it from happening again.
I have a house; I just want to remove "again" from that last phrase whenever possible so guys like us can enjoy their houses for a long time. There will always be risks in racing but some can be eliminated with a little preventative effort.
