Untitled Sighting

December coon hunt on Fewtown Road on the dog training grounds me and 3 buddys lost our dogs. The Garmin GPS wasn't working so we couldnt track them, we waited for one of them to strike and heard our dogs strike a long ways away. Fewtown road is located in Atwater. We drove all the way to the other side of the hunting ground and walked into the woods about 400 yards. One dog ran to our feet with its tail tucked. These are coon dogs, they don't run from their quarry. This dog would not leave our side. We had one dog 70 yards away where he was treein a coon. He stopped strike [editor's note: hunting dogs wear strike collars that indicate to the hunter electronically when the dog has stopped moving] this is is when we heard the loudest groaning wailing call. We all stood there mouths dropped. We put the one dog on a lead and my buddy went to get his dog so we could leave I went with him to get his dog. The dog stood pointed the opposite way of the tree with is hair on his back standing straight up, then we heard the loud long wailing noise again. We were all scared by then and didn't feel like investigating the call. No other cars were there nor were there any hunters there. No other dogs and there are no bears in the area.
