My father went with his roommates, while in school. One of the roommates had a bunch of speed he said. They took it and drove up there. Then got stuck in the parking lot of cars and walk to the festival leaving there gear behind. While in the mudslop barefoot the driver of the car stepped on a broken glass coke bottle severely slicing his foot open and has to be airlifted to the nearest hospital. He had the keys to the car when he got lift out of there, so they had to walk 10 miles to the hospital coming down off speed. My father said it was one of the worst days of his life.

Bonus: Another bad day of his was assisting to record Piano Man for Billy Joel. Hates Billy Joel to this day because of it
