Calf Scramble, the title of Libby Carr’s dynamic new work, is a double entendre. On one hand, it is an event, familiar to many a rodeo goer, that features teens chasing and roping calves to take home and raise as potentially profitable livestock. On the other hand, it is a fitting description of the play’s intent. Five high school girls find themselves as penned in by their circumstances as the calves are by their metal fences. The animalism of humans becomes jumbled with the humanity of animals, and if, at times, Carr lays on the symbolism with a heavy hoof, one must remember that the play is set in Texas, where everything is bigger, including the metaphors.
