We drove into town for a walk around the University of Michigan's Central Campus before dinner. We walked through Nickel's Arcade with its quaint shops and across the Diag — a large open space in the middle of the university's Central Campus. This is where, NORML , the National Association for the Reform of Marijuana Laws, holds the annual "hash bash". The Hash Bash began when poet John Sinclair was jailed for marijuana possession, leading John Lennon and Yoko Ono to headline a protest rally in Ann Arbor in 1971. Part political movement, part hippie love fest, excellent place to "not inhale".
