North Dakota doesn't have State Police....and if those troops were stopping people for no reason they (and the State) would be sued for civil rights violations.
I guess the way that I look at it is, if you can't respect our country enough to know the laws, stay in Canada. Don't let the USA door hit you on the ass on the way out.
In other news, I'm taking I-57 east tomorrow and then taking the I-84 bypass around Mayville. Then I'm going to take I-39 north to Grand Forks.
