The prices we pay for gasoline in Louisiana continue to slowly rise. Louisiana AAA fuel analyst Don Redman says an internationally-weak U.S. dollar and the ongoing debt ceiling disagreement in Washington, D.C., are to blame. He says those two factors have had crude oil and retail pump prices on a roller coaster. Redman says that's contributed to much lower demand for motor fuels, and has had a chilling effect on local and national economies. Redman says pump prices could fluctuate up or down by a few cents through the summer, but he says we should get used to them being well over $3. The statewide average for regular unleaded gas is $3.58, up a penny from Monday, and up a nickel in the past seven days.
