It runs along a curved sidewalk and has pipes of different length that sound the notes of a piece by Bach when walking and dragging a stick along the pipes.

I heard a story about a guy in a poker game that had a .25 cal bounce off his forehead, maybe in SC or Alabama. I don't recall any more details or even know if it really happened, but is sounds plausible. I guess it ain't a party till somebody starts shootin.
