So when I lived in MD we would ride our motorcycles into Gettysburg often. We were there one day just walking a path looking over part of the battlefield and saw some guys getting ready for what we thought was a reenactment by the tree line. We thought cool wonder when it starts so we start walking back to where our bikes were to ask the Park Ranger and the local cop that were thewhen we parked to ask when it started. So we asked them and they said there were no reenactments that day. We told them what we saw and so did a few other people who saw the same thing. Next thing you know police and Rangers are down in the area looking for these people. They came back with nothing. We apologized for the waste of time but we knew what we saw. The reply we got was. This happens all the time all over the park. We spend more time chasing ghosts than criminals! We had a good laugh. One of the cops recognized me since a week maybe 2 earlier a lady ran me off the road while she was driving and taking pictures. That was 1 of the 3 national battlefields I've wrecked on.. lol
