I'm thinking of going to the southwest US for the winter. What kind of seasonal/temporary jobs might I find there to do for a few months? I'm NOT interested in volunteer-camp-host type jobs, I want an actual paying job. I don't really care what it is--driving trucks or tractors, mechanical work, farm work, whatever--just so it's not sales.
