The May House is located almost directly across the road from the Pizza Hut in Prestonsburg. It has recently undergone extensive remodeling and is now a prized landmark for the community.
I don't think they would let anyone near it with a detector. I worked as a surveyor in the area of the college when they were building the science center and never thought of looking for relics and stuff. That whole river bottom should be full of items. Got a place near by in mind though...lol
