LA CROSSE, Wis. -- If you've been wondering if or when the prices of gas is going to go down, you are not alone.

Even though the summer travel season has come to a close, gas prices in Wisconsin are at the highest point point they've been in the last 5 months.

That hasn't stopped travelers like Carrie and Dave Damm from wrapping up their summer with a cross-country road trip.

"We've had this planned since last summer, that we would do a road trip out to our son and take him some stuff since he's moved to Colorado," said Carrie Damm.

The Michigan couple stopped at the French Island rest stop Wednesday on their way through our area. It was one of many stops along their journey, totaling more than 4,000 miles by the time they're back home.

The Damms don't even want to know how much their trip is costing in gas.

"You pay attention to your mileage and what you're doing but you know we'll scrimp somewhere else when we get home. The trip was worth it," said Carrie Damm.

The average price for a gallon of regular gas in Wisconsin right now is $3.94. It's $3.84 in the La Crosse-area.

Experts expect prices to drop by the end of the month and they have a guess on how much based on past years.

"Generally, it will drop around the mid-part of September. For example, last year, from September 1 to the end of the month, we dropped 35 cents a gallon," said Cheryl Thienes, a field manager at AAA.

Thienes says Hurricane Isaac has kept prices higher than expected in recent weeks.

"Any tropical storm, like we just experienced with Isaac, does have a tendency to cause some complications. Usually it will tend to effect the refinery or the shipments and that will increase the possibility for gas prices going up," said Thienes.

One year ago, the state average for a gallon of regular gas was $3.77. That's 17 cents less than today.
