Every Sunday between 2-5pm, people stand up on a soap box (milk crate) and speak about politics, religion, you name it. This has been going on since 1878. Anyone can get up and speak (bring your own milk crate), debate with the speakers or simply grab a spot on the grass and watch. You get UFO nuts, aspiring gurus, religious zealots, would-be intellectuals, to name a few. Hecklers are welcome.
Great free entertainment with a long and colorful history. Highly recommended.
