I don't think I am that brave lol.  If I did go, I likely would wait out in the car with a crucifix, garlic, anything I could think of.  A few at work want to go, but I think I will wait for the pics lol.  Now....if it were UFO stuff.......that I likely would check into.  can you take pics of the inside of your house and see if anything turns up Tonia?
