(Lansing, MI)  --  It's costing several more dimes a gallon more to fill up the gas tank around Michigan.  Political unrest in Libya is the latest reason being cited as the price at the pump has jumped to as high as $3.60 a gallon.  Prices were a little over three dollars a gallon in much of the state yesterday morning.  The website www.gasbuddy.com reports the highest price in Michigan is $3.59 a gallon at a station in Charlevoix and another on the west side of Lansing, while others are around $3.40.
