As you come into Lemmon SD on Hwy 12 from the east, the local police officers and local SD HP like to sit on the south side of the Hwy 12 in the parking lot of a closed mechanic shop across from the SD DOT Shop on the north side of the highway. From the east the speed limit will go from 65 to 45, and then to 35 very quickly coming into town and they love to nail people as they have to drop from 65 to 45. It is hard to see them sitting there until it is too late, so be aware of the area. I would avoid Lemmon if possible and travel either south or north if heading east/west as there are 3 Police Officers, 1 HP, and 1 Deputy Sheriff all stationed there for about a town of 1400 people.
