Water:
Too darn much of it. Over 10 inches of it. Enough to send me off to the rental joint for a sump-type pump for the back yard, and a turbo fan to dry out the pad and the carpet in the library downstairs, and for Susan to dig a canal in the back yard to drain the sucker and decrease the water pressures. I still hear the sump inside running on and off as I write this. &!*@!!
