"Everyone stood outside about one-hundred feet away from the tunnel and talked for a little while when the investigation was finished. I was very glad to be out of there. But I kept looking back, feeling as though we were still being watched from inside. I took a few more pictures of the tunnel entrance before we headed back to our cars. When I reviewed the photos from inside the tunnel I only noticed insects, water droplets, and a bat. Looking at the final shots I had taken from outside peering into the empty tunnel, I was suddenly covered in goose bumps."
