Have you ever encountered anything ~*supernatural*~?
If so, what was your reaction?
When I was in high school a friend and I discovered a tunnel under a never-completed stretch of highway full of huge graffiti murals dated, one per year, back to the 1980s, and littered with plastic furnature. We have gone back a few times, but the tunnel never seemed to be there unless we need a place to stop and rest our feet. It wasn't a small tunnel, ether, the openings being 20 feet across and unblocked, and the ceiling 20-30 feet high. It's just that it seems to be replaced with an empty, unpainted tunnel.
I miss Graffiti Tunnel :(
