Before I took this job, I was told that the cost of living out here is low... maybe my rent was 1/2 of what it would be in, say, New Jersey... but fuel and groceries are ridiculous out here in NW Pennsylvania.
Not only is fuel inexpensive here, so is rent/mortgages, electricity (about $100/month), groceries and etc. Plus, we’re the job king of the US. Property taxes are a little high because of how they spread money around to all the school districts, though.
I think the idea is that land is so cheap you can grow much of what you need and heat your house with wood or anthracite.
