Well it seems I just have a knack for drawing the Law to me.
I was out on Surrender Road in Yorktown in one of the huge fields about a 1/4 mile from the road throwing a ball for the dogs to chase. I was behind a hill so not visible from the road.
As I headed back to the car I saw a Park Ranger stop next to my car and turn on his lights. He saw me coming across the field with the dogs on leash and got out of his car, faced me, and put his hands on his hips and jsut stared as I walked across the field.
At about 25 yards I said "Hi" and he said "Mind telling me what you are doing?"
Long story short, I was not parked in an approved parking area and was not supossed to have the dogs off lease (I told him I was letting them chase the ball).
He asked for licence and registration and had me stand by my car while he ran it.
In the end he gave me a warning and let me know he could have fined me $100 for "off roading" in a National Park and $75 for each dog off leash.
He was an ok guy and we wound up talking a while after he got the offical stuff out of the way. He told me to park in an official area and as long as I was off the road they really didn't mind folks letting their dogs run as long as they did not get complaints. He even told me about a couple of fields off the beaten path to check out in the park.
