On Hwy 550 going South exiting Bloomfield, NM
After driving through Bloomfield, you will come to the outskirts of the city where the speed limit is still 35mph. Once you go over the bridge for the San Juan River, you begin to go uphill and notice the speed limit sign of 50mph. However, the cops sit just before the sign and pull you over. They say the speed limit is not 50 until you get to the sign.
