Cement

This is the creepy staircase in the parking garage (bottom). Walking through here is certainly the low point of every day, as you could imagine. It's always damp and gives me that public pool locker room feeling. Specifically Gath pool in Newton (top). It also reminds me of how much I HATE walking around with wet feet.

When googling around about cement I found this. Technically it's on Yahoo but you get my point.
