Black Cavalier had such a good idea so I'm going to take him up on it.
I will have a letterbox only available at the Haunted Castle in
Lincoln California see previous post for directions.

This stamp will only be used at the 2006 haunted castle so it is
limited edition.

You must go through the haunted castle and find me to receive the box.
I think I'll be in the room with the TV and the Dude in a Lazyboy.

Happy Haunting
