There's no doubt some people have left because of layoffs. But rent declining hasn't caught up and its hard for a family to continue to pay $2,000-$3,000 in rent. Its easy to hitch up the rv and head out of town from the rv park that they were paying $800 a month for a spot.
Lots of people probably heading to Minot to find a job, save on rent, be able to find single ladies and feel safer. Knowing they could always head the short drive back west if they're able to find an oil job again. http://america.aljazeera.com/multimedia/2015/4/north-dakota-hard-times.HTML
