It's a Halloween tradition on par with eating too much candy or vandalizing a storefront. For decades "The Rocky Horror Picture Show" has given men who otherwise wouldn't be caught dead at a musical the excuse to wear stockings and sing along. It has empowered otherwise bookish women to wear corsets in public or dress in drag. It has given even the shyest theater kid a sense of belonging and community, if even for a few, makeup-smeared hours. So tonight, be part of the fun as you can expect plenty of costumes, audience participation and an all around good time. Doors open at 11 p.m. The show costs a mere $5.
