Last night at a fatal MVA on the Northern State Parkway TG-3696 poped up with a Troop L unit requesting that "Farmingdale" [Troop HQ] have "Inforn" [highway information signs run by the state] put up the parkway closings on their signs. Since Troop L no longer uses their long time vhf [155.46] freq, is this a thing of the future?
