This area is over-run by Troopers looking for easy prey. Once you pass the Mountain Home Post Office (maybe even a bit before that), heading north… watch out. It’s a wide open 4-lane highway with really nothing on it until GB Shoes and the limit is only 45! They use unmarked cars a lot and will even hit you with the radar while they’re driving south and U-turn when they got you. I can’t believe this is even legal because they’re not keeping anyone safe by doing this. And most highways like this in other places have limits of 55 and higher! Please use caution!
