Very well put about the number of actors needed for haunting, would work great for a haunted house. I however ran a haunted trail last year that simply got way to big (long) and there were many nights where we needed 15 actors and no less for all of the nights, but most of the nights we were lucky to have 10 so for some haunts it does not work.
My family and I went to Wisconsin Dells this summer, and there just so happened to be a few haunted houses that you could go through. So I just had to go check it out, lets just say it was a waste of money but it's a nice example of what was said about actors. There was ONE, YES I SAID ONE person that did ALL the scares, no I was not impressed but my wife sure was scared LOL!!! But she does not care to much for haunted stuff, yet it's funny she will be the first to say lets go!!! She say's I don't like getting scared, well thats the whole reason why you are there and pay them money.
Anyway it's a VERY important subject that gets overlooked and needs to resurface every once in a while.
So thanks for that!!!!!!
