Dad watches a lot of the History Channel, and so we were watching a show documenting what would happen if humans suddenly disappeared off the face of the planet.  Apparently, the subway tunnels would start to flood in 36 hours and the damage of the water would cause the streets to collapse into the tunnels in 150 years.  Depending on the location, cars and buses would disappear in 75 to 100 years.  However, the most lingering aspect of humanity would be Mount Rushmore (and with that, I'd have to think Stone Mountain!).  I thought it was rather interesting, and therefore, needed to be shared.  I'm most surprised that the tunnels would flood so soon after we take leave.
