Gas prices have fallen a couple of cents in Oregon and Washington to around 3-71 a gallon, but Marie Dodds, with the Triple-A says prices could be on the rise again, soon.  Diesel prices also fell a couple of cents to $4.03 a gallon.  Dodds says that unless something causes prices to change, they should remain near this level through spring.  This week you'll pay an average of $3.69 for  gas in Bend.
