The Cotati Crawl, through the small downtown’s array of venues and drinking establishments, is a long-running tradition in Sonoma County—especially for Sonoma State students. This weekend, Leap Day offers a chance for a special daylong festival, the Cotati Gras, co-produced by Body Language Productions, in which 30-plus bands, DJs and artists take over spaces like Spancky’s Bar, with participating eateries and special offerings like a silent disco. Join in the festivities on Saturday, Feb. 29, along Old Redwood Highway in downtown Cotati. 2pm to 2am. Free. facebook.com/bodylanguageprod.
