Heading East on hwy 60 from Madison to Milwaukee I passed a state trooper backed in and hiding in a farm field driveway. He was gunning Westbound traffic. A mile up the road I saw a group of bikers heading at me. As we approached I gave the leader a warning signal much like an umpire signals a home run: pointing my finger straight up and making a circular motion i.e. signaling gumballs on top of a squad car.
