True, but the speed limit across much of South Dakota on I-90 is 85, which pretty much what everyone is doing, except the older Harleys. They just do the best they can.
Actually, the Speed Limit on I-90 in South Dakota between Rapid City and Sioux Falls is 80 mph. Between Rapid City and the Wyoming border, it is 75 mph.
This morning folks are creeping along about 45 mph past my house on I-90 between Exit 14 and Exit 12 due to a nice layer of icy slush.
