It happens again and again on the border of North Dakota and Northwest Minnesota.

You'd think after seeing that they'd learn to just move away and not rebuild on the same land. It's such a waste of tax money too! Good for you for moving to high ground, but you still have to live near people who don't learn the lesson. I don't think I could live nearby people who expect the rest of the world to help sandbag around their houses and such because they've chosen to live somewhere that is vulnerable to regular flooding.
This is a common theme around here - everyone just wants the short term quick fix, screw the consequences :o/
TBH I've been having occasional (once or twice a year) wierd nightmares about massive flooding coming through this area since I was a kid, and the creepy part was that when it happened this still didn't feel like "it". Like this is a small scale preview of things to come :o/
If we weren't reliant on so many services for the kids (special school, therapists etc) I would love to move inland somewhere like Mt Tamborine , much nicer environment and it'd take some serious end-of-days shit to drown me there :P
