As I crossed America and filled my tank in Iowa, Mizzery, Kansas, Texas, New Mexico and Arizona….Iowa’s prices are lowest (because of the states ethanol subsidy, running about $2.55/ gallon…and the clear winner is Arizona…in rural areas it runs right at $3/gallin but in Phoenix some places offer it at $3.40/ fallon but most run $3.60…. Any reason why Az gas is so much more expensive than the other states? And why is Phoenix gas so expensive??
