I just saw some nice, big photos of the Fargo flooding. I didn't realize before it was such a huge thing. But it looks massive.
Big blocks of ice in the river, the river spilling out everywhere, people wading in the water with the ice, houses surrounded by a tiny circle of sandbags and water everywhere, dogs stranded, looking sad, people working on sandbags. And all of this in essentially winter conditions.
It's massive, and bad.
As for sandbags, I saw they had some big industrial strength sandbag type fences, filled with a Caterpillar type scoop thing. That's better than by hand. Making sandbags by hand is tough and labor intensive. I've done it. It's no fun. But necessary. Although it seems like there'd be an automated way to do it.
