Founded by poet Lawrence Ferlinghetti and Peter D. Martin in 1953, City Lights has been on the forefront of alternative culture since it published Allen Ginsberg's Howl and Other Poems - for which Ferlinghetti had to fight obscenity charges - and has proudly boasted a "banned books" section for years. A center of protest and a hub for people with revolutionary ideas, it's also a darn fine bookstore, with a grand selection of poetry, alterna-prose, and politics. It's a San Francisco landmark, so if you're even semi counter culture, it's worth a visit.
