The Rahad Robbery
I don't know if anyone is familiar, but the scene where Dirk, Reed, and Todd rob Rahad was supposedly based on the alleged robbery John Holmes was involved. Nothing came of the robbery in the movie, other than Dirk hitting rock bottom. But in the real life robbery, the man they robbed retaliated and killed several drug dealers associated with Holmes. The incident is known as the Wonderland Murders.
Just some background history, in case anyone is interested.
