Living in NM, the rural areas are really poor (Income ~25% less than urban), mostly agriculture (big trucks), and long distances to travel to get to gas stations. Combine that with all the young kids moving away (free lottery scholarships) and a higher than normal percentage of people on fixed income, and I'm only surprised the gas doesn't eat up more of their income.
