The one silver lining is that Sunday I got motivated to apply polyurethane to the two cabinets I've been building, and put them up on saw horses to make it easier. Thus they are currently high and dry. Go me! I did have to slog around down there picking some other boxes and pieces of wood up out of the drink, but I seem to have caught it fairly early.
Now off to Home Depot to purchase some sort of pump. I don't think the wet vac is gonna do it this time.
