It Only Hurts When I Blog

Greetings, Bloggy Ghouls and Boys!

I want to invent a ghost walk for a retreat next year.

I have already started to collect the necessary stories, but I am wondering about little things that would make their experience more fun.

For example - is there an easy way to make a 'paranormal activity' monitor to gauge surrounding spirit activity?  (to answer my own question, a memo recorder playing static or geiger counter noises would work)

Do you have any good ideas from ghost walks you have been on?

Comment away! 

If I don't get any comments, I'll know you have ultimate faith in my creative energy.
