"After the speeches, about 50,000 people set off for the Pentagon. It took them about an hour and a half to walk two miles across the Memorial Bridge and down a service road to the north parking lot where a second rally was scheduled.
At the other end a group of hippies was trying to exorcize the Pentagon. The brainchild of Abbie Hoffman, the plan was for people to sing and chant until it levitated and turned orange, driving out the evil spirits and ending the war in Viet Nam. The Pentagon didn't move."
