Missouri has a bad reputation in Nebraska, for pulling stunts.
In Nebraska, one usually gets a mile, or half-mile, warning that the speed limit's going to drop on down the road.
In Missouri, in some places, within six feet (or so it seems), the speed limit drops from, say, 60 mph to 25 mph, no advance warning.
Also, I've heard that one gets speeding tickets in Missouri for going a mere one mile an hour over the speed-limit.
For out-of-staters coming to Nebraska, the informal rule is that that, for example, in a 60 mph zone, anything up to 64 mph is ignored; anything between 64 mph and 67 mph is chancy, and over that, it's a sure thing a cop's going to stop you; usually a warning if one has no recent record, but a ticket's guaranteed if 70 mph or over. In a 40 mph zone, anything up to 42.5 mph is tolerated and ignored, for another example; between that and 45 mph is dicey, and a ticket for sure at 50 mph and above.
