I drive through Lusk 5-6 times per year, and it’s always the same. At least two patrol vehicles going up and down US 85 through town clocking traffic, and at least one more hidden on a side road running radar, often 4th St. (police station) or 10th St. (gas station parking lot). Very aggressive in my experience–peg your speedometer 2-3 under the speed limit and check it frequently, as this sleepy town appears to make full use of its only obvious revenue stream.
