Gas prices are soaring.   Marie Dodds, at Triple-A, says it's all due to unrest in the Middle East, and specifically what's happening in Libya. Diesel prices in Oregon also increased 14-cents a gallon to $3.83. Hawaii has the highest average at $3.77 a gallon; California is second at $3.76. You'll pay an average of about $3.43 in Bend this week.
