There are four tunnels in all, the farthest one is dry. The entrance is an old brick tunnel covered with a ton of graffiti, which is rumored to be the home of much satanic activity. The dry tunnel quickly turns into a flowing one. There is said to be a battle-axe down there, which is too heavy to be lifted by mortal men. While I've never found that, I have seen an altar room, which is covered with murals.
Tunnels lead in every direction.
Red Eyed Mike is the spirit that guards the entrance of the tunnel. If you knock on the railroad ties above the entrance three times, you will hear a loud horn blast emanate from within the tunnel. I have heard this horn, not every time I've tried this, but it has sent me running so fast that I nearly broke my leg. I've also encountered rocks being tossed out of the tunnel with no apparent deliverer. I've also seen a small figure, about three feet high, sprint out of the tunnel faster than any human being can move, and take off towards the tunnel that leads to Weasel Brook Park.
