Gas prices keep climbing.
Many gas stations around mid-Michigan reached $3.99 a gallon on Thursday and experts say the prices could stay that way for weeks.
We caught up with some drivers who are already seeing the effects of higher prices.
James and Pat Jennings love to travel.
They're on their way back from vacation in Charlevoix and they're driving and SUV and pulling a camper.
James Jennings: “You're lucky to get maybe 10 to 12 miles a gallon.”
But when they left last week, gas prices were around $3.50 a gallon.
James Jennings: “Coming back it seen it went up to almost 4 dollars a gallon so that's kinda ridiculous.”
They expected to pay under 200 dollars in gas for the entire trip but instead the it cost them about 300 bucks.
And they're not the only ones who are fed up.
Rene Feehan, Driver: “It's terrible, I don't like the fluctuation at all. Just a couple days ago it was 360 I don't understand why its 399 today.”
Experts say the jump is due to issues at three regional refineries but drivers aren't so sure.
James Jennings: 'The excuse they have to have so the people have to pay for it.”
Feehan: “I think there's always another reason and I think that it fluctuates to prepare us to pay more.”
As for the Jennings, they have a road trip to Maine coming up next month.
Pat Jennings: “We canceled our trip to Maine a couple of times because of gas prices and when we planned it this time it wasn't that high and now here it is going up again.”
While they still plan to go, they say they may just have to cut back on other things.
And a recent AAA poll finds that 13 percent of Michigan drivers will change their habits to save money–
now that gas is between $3.75 and $4.00 a gallon.
However 26 percent said they wouldn't make any changes until prices hit between $4.00 to $4.25 a gallon.
