Custer, South Dakota Speed Traps
All schools are 25 mph. 24/7 all year. I got a 38 in 25 on a sat, at 8PM at night.
The South Dakota Highway Patrol likes to keep an eye on this area during holiday periods, and tends to drift between the Crazy Horse Monument and Route 244, the road to Mount Rushmore. If you are a tourist, beware of this.
