My wife worked in a psychiatric hospital while she was getting her hours for her MFT license. She hated it... they would get these 5150 patients in, stabilize them, give them a scrip, kick them out, and bill the state. It was unfortunately like an assembly line. In a place like the Dakotas things might be different just due to the weather... sleeping rough here is seldom going to kill you and because of that the sheer number of people sleeping rough is going to be higher in the first place.

If I have the time to worry about it I watch the hour by hour rain forecast and the radar and the expected rainfall... % chance for a day is a pretty wobbly number
