Drivers in Michigan are paying more per gallon this week. AAA Michigan says the average price rose about 2-and-a-half cents to a statewide average of $3.66 per gallon. The auto club's Nancy Cain says the higher pump prices this week haven't slowed down business at the camps and resorts for those looking to take a late summer vacation. Drivers are finding higher gas prices primarily due to fluctuations in the worldwide price of crude oil. Local pumps around the Blue Water Area began the week at around $3.66.
