The Tunnel of Love in Kennywood

The Old Mill is the oldest roller coaster in Kennywood Theme Park. It's one of these, you know, like a log flume with no up and down bits. You're just kind of slowly going round in the water. There might be skeletons or there might be sexy things on the side. And it's because they didn't want people making out all worse in their tunnels of love. Some of them were actually almost in the shape of a hand. I wonder for how many people who got slapped on the butt by the ping pong paddle that turned into an exciting new fetish?
