One of the easy lessons to learn in life is that when you walk out onto the ledge make sure that there is something down below in case you fall. Being out on the ledge is nothing new for Dale Gutzman and his tiny Off The Wall Theatre and he has never been afraid to walk out there without something to fall off. Gutzman is out on the ledge again with the opening of "Grey Gardens," a quirky musical based on an almost 30-year-old documentary film.
