Did you see me sandbagging back in the 1990s Jeff? Mississippi 3-5 miles wide south of here. We are very efficient at hanging drywall in the Midwest.
Down to the studs if you don't want to live in a swamp house. I only had to do that once in my first house. My current house is 50ft above Mississippi flood stage. Everyone comments how terrible my lane must be in winter. Yeah I'm cool with walking up the lane 3 or 4 times a winter. Good for my heart and drywall is bad on my back.
Flood damage is horrible. You can see from Silver's pics it's pure mud. The water leaves your house in a few days, the skanky mud stays until you remove it.
