As a local my advice is to keep the speedometer 1 mile below the posted speed limit no matter where you are in Jackson, near Jackson and especaially in Teton National Park and Yellowstone. The police here are nazis and will pull you over at the drop of the hat especially if you out of state plates. Also do not even think about driving with a few drinks in you. The 1st 5 words out of any of the police here whether its the Highway Patrol, Jackson Police, Park Police or the Sherif is "hello have you been drinking." About the only thing police around here know how to do is give speeding tickets and dui’s.
