I'd love to know what these nomadic folks do for friends and socialisation. I think I'd find it exceedingly lonely to uproot myself from urban civilisation (that includes the case of living in a new city every few month).
There are certainly areas you can go where lots of other nomads go (and then hang out with them). Quartzite, Arizona in the U.S. is the obvious example. I understand that, from there, you can caravan off with a group of like-minded nomads to the next destination.
Second picture from his camping trip should fully answer "what these nomadic folks do".
