Canadians are big business for border towns like Eureka in northern Montana.
Last year nearly 230,000 vehicles with some 357,000 people traveled into Montana through the Roosville Port of Entry.
But the heavy traffic can cause long wait times of nearly three hours.
State Republican Rep. Mike Cuffe, of Eureka, says the long waits can leave a bad taste in the mouths of visitors who might reconsider returning to Montana.
Cuffe tells the Flathead Beacon (http://bit.ly/1rjTVLg) that the situation is harming the flow of tourism and commerce.
He is spearheading an effort to work with the Canadian government to find solutions while gathering support on the American side.
Possible solutions include adding more staff to Roosville, creating an expedited entry system and adding a fourth lane for inspections.
