Well I live at the other end of that long road called the BRPW where it is called Skyline Drive up here in Virginia. I live in Maryland and I can pick up NPS LEO's when they use their radios even tho I am about 100 to 120 airmiles from skyline drive but with my Yagi pointed that way plus im sure they might be using some type of repeaters as well plus the NPS HQ for skyline drive is in Luray VA. What I really wonder is when a park ranger or LEO travels from skyline drive to where it switches over to Blue Ridge Parkway I wonder what radio system they would end up using??? since it seems to me they have legal authority along the whole 500 miles plus of skyline drive and the BRPW. Next time i catch a NPS Ranger or LEO i will take a hard look at the frequency that they are us plus has anyone ever heard of the US Park Police here in DC Metro transmit on the skyline system or viper? That opens a whole new can of worms as well. I used to live in a town called Fletcher in Western NC not to far from Mt Pisgah and BRP.
