[The Mothman]

My dad would always tell me stories of how the Rocky Horror Picture Show would play every once and a while in a theater where he used to live. he said that poeple would dress up in all sorts of costumes and just get real rowdy during the showings. This always sounded real awesome to me. The other day i was walking by a theater n Wellington and saw a sign for it. The sign encouraged people to dress up and so on, I bought tickets and am going to see it next week, i am pretty stoked considering I've never seen the film before, actually.
Has anyone heard of/been to one of these outings before?
