Find the highest price for unleaded gas - Wisconsin = $2.22 and your state?

Wisconsin, in addition to the above average gas tax, has a type of reformulated that is not easy to produce and the adds to the price per gallon.

This single best thing that the Federal government could do to control price is to enact a single standard for reformulated gasoline in the non-attainment areas. The market is strangled by the inability to transport gasoline from an area of supply to one of demand.

We had a spike in IL a few summers ago when the combination of a pipeline problem and refinery problem deeply cut the capacity to make the special formula required in the Chicago metro area. I could drive 20 miles west to save 40 cents/gal by leaving the non-attainment area. If gas could be moved more easily between regions the price effects would have been much less.

California is probably around $2.30-$2.40 around San Francisco (despite the infrastructure and density making it cheaper to get it there) and around $2.10 where I live, out in the middle of nowhere.

Odd. In Germany it tends to be slightly cheaper in the cities.

People in the cities have more money.

Logically speaking, it should be more expensive in the rural areas because it costs more for transportation and you sell less than in the city, so you need a higher profit margin.  However, the free market doesn't work with oil prices.

In many areas the cities are non-attainment areas, that is they fail certain criteria of the Clean Air Act. This forces gas stations in those areas to sell only special blends to generate less pollutants. Rural areas rarely have enough air pollutants to become non-attainment areas, so those stations can sell any blend.
