Oh I see! In the foreground is Timothy Leary and the shirtless fella is Neil Cassady. He was Jack Kerouac's sidekick on the cross country travels in, "On The Road". Kerouac's name for him was Dean Moriarty and Kerouac was Sal Paradise. Cassady also drove the Further bus for Ken Kesey and the Pranksters. Timothy Leary everyone knows what he did. He didn't disappoint either. As he lay dying he took his last trip!
