Celebrate your great American independence with an afternoon in a park packed full of stuff to delight and divert you and your entire goddamn family. Among the attractions of the 11th Annual Independence Day Picnic: free hot dogs (beef and Field Roast) from noon to 2 p.m.! A pie-eating contest! A pet/human look-alike contest! Group yoga! And music, from kid-pleasers (the Not-Its!) to bluesy punks (Gnarlene and the Frisky Pigs) to Brazilian jazz (Choro Loco). Wear sunscreen. (Cal Anderson Park, 1635 11th Ave, calandersonpark.org, noon–5 pm, free)
