Waldo had their speed trap when I was in college. This is as old as my lifetime. Everybody in the area knows about it. LOL!
The worst speed trap ever was Ludowici, Georgia. Nearby Jesup was almost as bad. Governor Maddox threatened to have the town abolished if they didn’t straighten up.
They eventually did quit the highway robbery. Georgia also passed the “Ludowici Law” which banned local cops from issuing tickets for anything under 10 mph over the limit.
