Scary stop at an Auto graveyard

Scary because I stopped when I noticed this collection of old cars sitting by the side of the road.. I saw the keep out signs ok, but they were behind a fence, so I figured as long as I was behind the fence, I was ok...  Shortly a fellow came over from the other side of the road asking "What was I doing on his property?"  I explained just taking photos, and I saw the signs but I figured since I was on the road, and not behind the fence, I was OK...  He sort of said well, OK, then: "I've had a lot of problems with poachers... I told him I completely understood, and cut my photo session short right there...  too bad, there were about a 100 more even older cars further on back down the road, but maybe another time.
