Free theater in the park offerings include two specifically for younger audiences. Theater Schmeater introduces An Inconvenient Squirrel by Joseph Scrimshaw, the tale of a young squirrel that refuses to conform to the village's naming traditions. Performances are at the Amphitheater at Volunteer Park, July 10-August 15. Open Circle Theatre presents Pirates at Princess Island (July 17-August 7) where everything is perfect and everyone is, well, a Princess. But when scurvy sea-dog Pirates storm the island intent on taking the gems and jewels for their own, what on earth might happen?
