U.S. Route 20 has a posted speed of 65 mph. If you make the turn left on to county road 31 (Marshall Street) into Manderson, if you don’t slow down right away, there a Manderson police car sitting, hidden, ready to pounce. The posted speed for Manderson was not evident. I was caught, the police said, going 13 miles over the speed limit (though I wasn’t sure what that limit was.) For the penalty, I was charged $181, which seems exorbitant. My wife and I are from MN and were returning home from vacation. This certainly spoiled it. There was a car behind me going the same speed. To make the turn we both had to slow down, and we both were caught. Be very careful going through Manderson, WY.
