Thanks for the good wishes.
I was very lucky since I had a few minutes between assignments and stopped home. If I hadn't, the whole place would have been wet, ruining my laptop, several cameras (laptop and extra cameras sit by the door in a "bug out bag" for assignments that require the extra gear) and a lot of other stuff. The computers are all up off the floor.
The only really bad part was that it took two hours for the building maintenance guy to show up. (He lives in the building across the parking lot.) Even then, he couldn't shut off the water properly and didn't offer to lend me a shop vac.
The place stinks and the hall carpet is still wet. The only real damage was to the building itself and that's the owner's problem. He needs to hire more responsible people. Beside the water damage, the plumber burned a hole in the kitchen floor with a propane torch.
Stats will be back tonight as usual.
