Coming off the Van wyck onto nassau expressway by JFK today, I was lucky enough to see a cop standing there with a radar gun pointed at cars coming down the road. I managed to slam on the brakes, but I just want to give you guys a heads up in case your in the area. You usually dont see any cops in the area, this time he was hiding. It was especially scary to see him just standing there pointing his gun at you. He might be back tomorrow, he might not... just be on the lookout.
