Rob,
It's good to hear from you! I bought windshield wiper motors from you and love them. I've built (well almost built) a crate monster and am using one of the motors to drive the cam that shakes the lid.
I've spent time at the Home Haunters Association site but am still waiting for the launch of the Home Haunt Club. The Association seems to be evolving as an index to resources for the sub-charity haunt crowd. Me for example

. They have a home haunt registry and big collection of haunt videos and projects.
My understanding is that the Club will have a different focus. Since I need all the resources I can get, I'm anxious to see what they'll provide too!
