I bet he was messing with the apparent OM fan that works inside the building where he is parked. Look at the door/window to the left of the car. It says KKK on something on the inside of that glass. Zoom in.
I have a SDS sticker on my truck, I like it a lot. Picking up a new bulldog decal (the old one had faded and cracked) to put next to it this weekend. To each their own I guess.
