Looking for something to do this weekend? Here are a few selections from contributors across the state. Katie Friel, Managing Editor of CultureMap Austin says you should go see “The Mountaintop” at the Austin Playhouse. If you’re near Waco, Kathryn Jones, contributing writer for Texas Highways Magazine, thinks the Mammoth excavation site should not be missed. Folks in the San Antonio area should check out the Strauss Festival at the Tobin Center for the Performing Arts, per the advice of Rebecca Fontenot, Editor in Chief for San Antonio Magazine.
