The recent spike in gas prices has resulted in an unusual occurence…Wisconsin’s average price at the pump is higher than the national average. State AAA spokesman Nick Jarmusz says the recent jump in prices is due to refinery issues ranging from planned maintenance to following a refinery fire. Jarmusz says prices should start to stabilize again once the refinery comes back on line. Two weeks ago the average price for unleaded regular in the Fond du Lac area was about $3.22 cents a gallon, but is close to $4 a gallon today.
