7-25-12  --  In the continuing saga of rising and falling gas prices, Minnesota now has the dubious distinction of having some of the highest prices in the nation.  Minnesota-Gas-Prices-dot-Com reports regular unleaded is now up to 3-67 a gallon on average, joining the ranks of pricey states on the West Coast and in New England.  The national average is over 15-cents less.  A bit of irony to the west of Minnesota -- North Dakota, which continues to roll in the financial success of its oil boom, features some of the highest pump prices in the country, specifically in the area of the Williston oil fields.
