We saw a recent Friday night "Theatresports" show and had a great time on our first night in town having flown in from the east coast for a long weekend getaway. We walked over to the Fort Mason area after having dinner near Fisherman's Wharf. There was a good crowd (about 2/3's full) -- I hear they sell-out on Saturday nights. Well worth the price of admisson with the show starting at 8 and ending a little before 10pm. A good sized theatre with comfortable seating. The two teams were enthusiastic and creative in their "competitive" rounds of improv. The teams involved the audience and gave people several chances to participate -- some even invited to join them on stage. No one was hassled or felt forced to join in -- clearly voluntary. We enjoyed the evening and highly recommend you stop in to see a BATS production if you're in town on a Friday or Saturday night.
