CHEYENNE - Wyoming doesn't have the cheapest diesel prices in the country, but plenty of truck drivers are still stopping at stations in the state.

Mike Hawkins, a truck driver from Alberta, Canada, who was filling up at the Flying J in Cheyenne on Monday, said that because his truck can hold more fuel than most trucks, he's very careful about where he'll stop for gas.

Hawkins said he goes online to check prices along his route, and that Wyoming is almost always one of the cheapest places to fill up.

"It's the difference between making money or losing money," Hawkins said. "You have to do your homework."

Hawkins said he knew of several other truckers who have been forced out of the business because they didn't study up on gas prices at different stations.

Jeff Zwolensky from Owosso, Mich., said he might get out of the trucking business soon if fuel prices don't come down.

Zwolensky spent more than $600 filling up his truck Monday.

"It seems like the government could do something," Zwolensky said. "If they can't get it under control, I'm done."

Lester Surface, of Jefferson City, Mo., said he used to be careful and check prices throughout the country so he could fill up at the cheapest stations. But now that doesn't seem to make much of a difference.

"It's high everywhere," Surface said. "There's just no reason for it to be like this."

John Huber, a driver from Ste. Genevieve, Mo., was equally perturbed. He regularly drives between St. Louis and Reno, Nev., and said prices are the worst they've been in his 27 years of driving.

"This is just ridiculous," Huber said. "Americans are eventually going to have to stand up and say enough is enough."
