I totally believe Grant and Jason, simply because they don't find something everywhere they go. There are a lot of times when they will decide since they didn't catch anything it could have been the wiring, or something like that. I like that they don't use psychics, but go only by what can be documented. In my opinion, the collar pull happened.
Brian annoys the heck outta me. He never goes anywhere that doesn't have something going on. His reliability and honesty are questionable to me, so if he sees something (which he always does), I never believe it unless someone else sees it/hears it/etc. too.
Ready for GHI in January and GH in March!
