I was just wondering what the origin of a ghost light was? Keeping a random light on stage all night dosen't seem like it has a point... just seems like a waste of electricity... Is there a reason for it? Personally, my school dosen't keep a ghost light on, but we're also a gym/cafeteria/theater, so thats another reason. The local theater i'm starting to do stuff at keeps a ghost light on at night. Yea, i'm getting side tracked, Anyway, whats the point of it?
