I had to make a weekly trip to Lancaster, Pa, today and took one of my dogs with me. On the way back, we stopped at a local park to hike. We walked about three or four miles and just when I thought the trial ended, it picked up again a few feet away and so we kept walking. Eventually, we came across a guy from the USDA who was cutting some leaves for samples to study some bug that's killing maple trees. We talked for a few minutes and I told him that I was really surprised that this trail went so far, and explained that I have lived in this area for twenty years and had no idea all this was here. I truly thought the trail only went for a couple of miles, but he laughed and explained that it's called the "blue trail" and is a part of the Mason-Dixon Trail that goes on for several hundred miles, that if I kept going, I could walk one way all the way to Maine and if I went the other way, I would meet up with the Appalachian Trail and could follow that a couple hundred miles to its Southen end. I've lived here for about twenty years and had no idea this was right outside my back door.
