Mansion Tunnels
I was told a few years back that old lumber baron mansions in Bay City, MI were connected by tunnels. I was also told that they still exist and are still used. There are also tunnels nearby under hell's half mile on the river front. I was looking for help confirming any possible portals of entry. Anyone up for the challenge?
