As you are driving North on Telegraph the speed (for no reason) drops to 40mph from 50mph. The cop usually sits in the parking lot of the business near the mobil gas station . This is about 1/2 mile South of Voorheis Rd. It doesn’t take the cop long to find a speeder as people normally do 50 through here. They usually just leave the radar unit on so you can pick it up ahead of time instead of using instant on.
