For 20 years, the folks of Farm Sanctuary have saved all manner of animals from the cruel conditions inside factory farms. But rather than illegally breaking in and cutting locks like some animal rights organizations, Farm Sanctuary saves animals by changing the laws themselves. The national organization was a key player in the 2002 Florida ballot initiative outlawing gestation crates — two-foot-wide metal enclosures where breeding pigs are confined, sometimes for years on end. But fighting the farm industry is an expensive venture, so local animal lovers invite like-minded people to participate in the 2006 Walk for Farm Animals in St. Petersburg to raise money for the nonprofit. After a short walk from Vinoy Park to The Pier and back, stick around for the vegan potluck and enjoy the most guilt-less couscous you've ever eaten. Sat., Sept. 2, 10 a.m., Vinoy Park, St. Petersburg, $10 to register (includes T-shirt), 813-810-5396, www.walkforanimals.org.
