Via the folks at Paranormal Practice.
I'm related to one of the folks involved with this project, and they're (the individual, that is) always asking me about haunted houses and where to find them. So, in the event that there's a place you think just plain needs some EVP recorded within, drop them a line!
All that said: man, why the hell am I not trying to spend all night in haunted locations and do EVP recordings?! Although, truthfully, I'd rather try using things like U.D.'s Gaze Techniques found in the first volume of High Magick: Theory and Practice (or Jason's version of very similar techniques) at such a place.
This makes me seriously ponder if I could ever, in any sort of good faith, claim to be a psychic and join such an excursion. I really don't think I'm psychic enough, when you get right down to it.
