Came through from Winthrop yesterday. A lot of radar activity between Newhalem, Marblemount and Concrete. I think they were working in pairs. You see the first car, hopefully, and figure that they are now past and you are safe so you pick up the pace only to find about .5k behind the first car is a second one with radar also working. They keep in radio contact and the first lets the second know that you are coming and they watch for you. So....be careful. These places, as most older riders should know, are notorious for LEO. If you are new to this particular part of highway 20...keep a sharp eye. I very nearly got caught by this trick.
