Saturday, July 20: Grab your top hat, corset and perhaps a towel or two for the Greatest Slough on Earth, aka the Rivertown Revival in Petaluma. Hard to categorize, it’s a theatrical one-day event that includes art boat races on the Petaluma River (read hand-built contraptions of dubious water-worthiness), aerial acts, indie band performances, food, beer, wine and of course, $5 weddings. Yup. Really.
The event lasts from 11am to 8pm, and creative costuming is pretty much required. $5 entrance fee, Steamer Landing Park, 6 Copeland St., Petaluma.
