From the couple of times that I've been there, I've only noticed water level markings about one or two feet higher than the usual level. And the usual level is typically about two or three feet below the "floor" in most of the connecting tunnel, so you should be safe. ( Unless the melt from the blizzard deposited an unusual amount of water in the complex, but I doubt that. )
Telling a man to get lost, and making him do it are two entirely different propositions... 52389, 118604
