Thought I'd share--
We just had a big tado in our town about some members of the "Ghost Hunters" visiting our small town and staking out the local haunted playhouse. The ghosts name is "Oscar" and he died in a fire that occurred during a performance at the theater. While no ghosts were actually filmed, the hunters left with high readings on their instruments and the paranormal investigators are sure they felt the presence of a ghost.
I have been to the theater and even performed in plays there.... while I have never experienced any paranormal activity myself while in production, many of the patrons and actors will not stay in the dressing rooms alone, nor will they perform during the month of Oscars demise. Historically this is the time that "Oscar" is most active. Moving or hiding props, turning on and off lights and causing general chaos during performances. The back staging area is frequently ice cold while the rest of the theater is snugly warm. (this I have experienced)
The investigation made the front page of the local paper in my hometown. Pretty cool in my book :)
