SFist Tonight

ART: It's your last chance to view the current exhibitions at SF Camerawork. The Summer Exhibition Cool-Down Party features Ersatz Group Exhibition, Leaving A Mark: Cutter Photozine, and The 2009 James D. Phelan Art Award in Photography. The publication of the Ersatz exhibition catalog will also be announced.

5 to 8 p.m. // SF Camerwork (657 Mission St, 2nd fl) // free

LIT: Actor, activist and Mill Valley-resident Peter Coyote's memoir Sleeping Where I Fall discusses the Diggers, a group he helped create in 1960s Haight-Ashbury, who distributed free food, provided free medical care, and sponsored free rock concerts in Golden Gate Park featuring musicians like the Grateful Dead.

7:30 p.m. // Booksmith (1644 Haight St) // free

THEATER: Lisa Rowland and Dave Dennison bring us Awkward Dinner Party, a blend of short- and long-form improvisation in which the two have invited another couple over for dinner, but only one member (Rafe Chase) shows up. Hilarity and discomfort ensue. The show runs through Saturday.

8 p.m. // Noh Space Theater (2840 Mariposa) // $15-18, buy tickets
