If you mean the North Charleston Coliseum Performing Art Center (http://www.northcharlestoncoliseumpac.com), CC is a no-go there. The building, though managed by a private company, is publically-owned and is thus off-limits. Yet another reason why we need to get the law changed to allow carry in publically-owned buildings. The SC Acquarium is similar--state-owned building, privately run=no carry.
