I have investigated this tunnel numerous times, daytime and nighttime, along with a fellow ghosthunter, and i have alot of pics with ghost orbs in them, from both night and day. one part of the tunnel about 1000 feet in , there is a place about 10 feet long that the temp will drop dramatically and make hair stand up on your neck.I have alot of pics with apparitions in them, anyone wanting to view or wanting to get together to ghost hunt, let me know at cb26354@aol.com
