Enter: Ken Kesey.
We learned about Ken Kesey and his crazy life today (even though he was clean shaven.) He is an author who wrote the novel, One Flew Over the Cukoo's Nest. Which inspired one of my favorite films starring Jack Nicholson. He took part in a government program where they would test LSD on different people, thinking it would become a sort of truth serum (like veriteserum in Harry Potter?). Yeah, you read that right, LSD. They often administered the drug to people without their consent. Like "Oh surprise! I just gave you some LSD, have a fun trip!"
He became the leader of a group called, The Merry Pranksters which was a group that supported drug use. In the early 60's they rode across country from California to New York on a insane magic bus (that inspired many other magic buses) and went on a long cross country trip (pun intended.)
They would take LSD in Kool-Aid and try not to freak out as they listened to The Grateful Dead traveling across the US.
