The average price for gas in Oregon increased last week nearly 4¢ a gallon to $3.68.  The Triple-A's Marie Dodds says we could be paying $4 a gallon this summer.  The unrest in the Middle East is the main reason prices are continuing to increase. Diesel increase 2¢ a gallon to $4.10.  We have an average of about $3.65 in Bend right now.
