I know.  I live in Utah.  Arizona is even cheaper than Utah and that makes no sense.  I used to work for an oil refinery and I learned that there is a pipeline that services Idaho, Utah and Arizona.  They are selling the same gas that Utah and Idaho is selling and yet it is about 75 cents a gallon cheaper in Arizona.  I was in Show Low, Arizona last week and that is where I saw the cheap gas.  I don't know what gas prices are in Phoenix or other areas of Arizona.
