I chatted with a motel owner in the middle of nowhere, Arizona who made his yearly nut off seasonal melon pickers, usually Mexican nationals on agricultural work visas. They need a place to stay, too. Otherwise, he had the kind of quiet, far out of the way old motel you see in horror movies (which I particularly love) and the odd foreign film set in America.
I ran into traveling road crews (as in CalTrans contractors building highways) visiting a facility for my current employer. Interesting crowd. The pay is good, and the only real requirements seem to be the willingness to wake up early, work hard, and not be insufferable to work with.
