as you approach Surrey after leaving Minot
There is only a 2-mile stretch of 70mph, after Minot before approaching eastbound to Surrey, then speed changes to 60mph. This non-distinct stretch of highway is wide open space and is a four-lane, with wide ditches, and with very few crossroads or signs. The patrol hides over the crest of the railroad overpass (2nd street) and seemingly targets out-of-staters. (satellite image and street-view to see what it looks like). The question is: Why open to freeway speed for such a short distance if it was not to promote ticketing?
