Friday Happenings

Hippie Dancing

-- Bostonist has never seen more atrocious dancing than we did when we stood outside of Cambridge City Hall last year and watched the slowly flailing arms of a thousand hippies moving in whatever the opposite of unison might be. Tons of fun for people watching. Cambridge City Dance Party, Central Square, 7:00pm-11:00pm. Free.

Bicycle Art

-- Bicycle art is having some sort of renaissance across the country, and you would be remiss if you ignored Boston's contribution to the fad.
