Oh, I almost forgot.
Saturday evening, we ended up at the bar to clean up the pond that had formed the day before. We loaded up a bunch of spare towels, made hydrodynamic drawings of where the water will flow and at what rate, and how much erosion the moving water will create on the concrete floor.
But it was all for naught. When we opened the door to the bar we saw the water had all but vanished. Poof!
It's still a problem that we need to correct (where is the water coming from??) but that it vanishes within a day is a good thing. It also says to me that we do have a water problem in the bar and that those times in the past we've gone down expecting to see large puddles of water but didn't see anything just means that the water that had been there just went somewhere else.
