Or walking on top of it. The DUMBs and tunnels everywhere unnerve me.
Makes me think of the old detroit salt mines.
That salt deposit goes under Lake Huron from Detroit all the way to Drummond Island off the tip of the UP. It is closed to the public these days.
Wow! no shit? I've always wanted to sneak into them.
