I90 west bound just past interstate spur into town
West bound as you top the hill just past the interstate spur going into Rapid City, a patrol car is often sitting in the median. As you give it the gas to climb the hill and top the hill you will often gain speed without realizing it right away. I have had my encounters there and have seen the patrol cars there often. I say cars because there is often two cars positioned there for both traffic directions. East bound often don’t slow down to the 65 mph speed as they come into the city limits.
