After Hurricane Floyd flooded a good bit of Eastern NC I went down to help with the cleanup on a couple of occasions.
The first trip was when the water was just going down in some areas. We went into a town that was still closed to the public. It was, well, a disaster.
Driving to this one town we had to go into an area flooded by the Neuse River. We found large fish in the road. The flotsam was 10-20 feet in the trees.

Wooden stairs from mobile homes where in the middle of farm fields with now homes nearby. Farm fields were BLACK. A diary farmer had lost 100 cows that had drowned. No way to save them a few of them had busted in the door of a mobile home to get out of the rising water.
That did not last long and the water went over the top of the home. The cows drowned inside. FEMA burned the homes down. Nothing else to do. I have a photo somewhere of cow ribs sticking up out of the ashes near the axle.
We got to one town that was hit real bad. Cars had floated up on to cars in some sort of weird Detroit mating game. Caskets and vaults had popped out of the ground in grave yards. It looked like a horror film. Smelled bad. Real bad.
It was very surreal. We had stopped to look at the caskets and vaults in a grave yard. The street was empty of cars since most of them had been flooded and the town was closed anyway. Across the street was a large lot. There was a foundation close to the street with a house towards the back of the lot against the woods...
It did not look quite right...
Eventually I figured it out. The house had been built with no anchor bolts and it had floated "downstream" until the trees had stopped the house "boat". The water had not "destroyed" the house but had set it down very gently so that it looked like it had always been next to the trees when in fact it had floated a 100 feet or so.
Course the house was destroyed but it was very strange that the house was built with no anchors....
Later,
