A really important issue here is that with any major evacuation (think Katrina), means of self defense, especially guns, are *vital*.
While these evacuees are mostly “honest people”, a lot of them are going to be ‘strapped’ for money and the essentials of life, wherever they have evacuated to. As soon as they leave, the clock is running.
An evacuation before a possible disaster is also a great time to evaluate the effectiveness of SHTF planning, so needs to be carefully watched to see what happens.
Right now it looks like nobody knows when the thousands of people will be able to return toothier homes. Returning to their jobs is also a huge issue for many, their employers being located in the evacuated zone. The inexcusable failure of Moonbeam to spend a piddling $100 million on maintaining that dam is going to cost billions now that repair is far more difficult than it would have been during the drought. Good God, weather's cyclical and has been since the time of Noah, with droughts being followed by floods and floods followed by droughts. Moonbeam never even thought of that.
