Imagine yourself traipsing through Golden Gate Park one sunny afternoon when the sound of the great Sylvester's "Can't Stop Dancing" tugs you by the ear toward the AIDS Memorial Grove. There you spy dozens of human butterflies, fluttering and whirling in the breeze as a DJ turns them out. Drawn by your fascination, you enter the fray, pick up a couple of psychedelic-patterned pieces of fabric, and begin to twirl with abandon. You're floating with Flagging in the Park, the charitable monthly afternoon flood of queer love, put on by personal trainer Xavier Caylor and friends. Like fan-dancing, flagging (dancing with weighted pieces of fabric) is a decades-old gay dance floor tradition that has taken on a spiritual edge, calling up the memories of those affected by AIDS and drawing the blessing of our own spiritual godmothers, The Sisters of Perpetual Indulgence. It's also simply fabulous.

Sat/30 and monthly, 1 p.m.–4 p.m., free (donation requested), AIDS Memorial Grove, Golden Gate Park, SF. Facebook: Flagging in the Park
