Pocono Raceway has long been known as the Tricky Triangle for good reason. It's been the site of some of the most spectacular, frightening wrecks in NASCAR history.
Here are the stories behind many of them:
Petty’s 1980 crash at Pocono is among the sport’s worst of all time. Petty lost a right-front wheel and slammed into the outside wall. He then idled across the middle of the track, facing traffic as other crashing cars tried desperately to avoid him.
Darrell Waltrip was unable to do so -- and his sliding car slammed into Petty's door.
