Seen that plenty of times.... it's not unlikely at all. You never know what the story might be.
Had an interesting one awhile back on a MTB road trip. There was a truck/trailer parked along the fence on one side. Rather than take up even more spots we parked alongside him. While we were riding the truck departed leaving a space between us and the fence. Some genius decided to squeeze his car into that space. But he didn't just drive in and park parallel to us like the truck had been. Instead he parked perpendicular between the us and the fence which could only have been done by pulling up to the end out our trailer and parallel parking inwards. Must have been his special spot. When we got back to the van there was a note from the BLM ranger telling us not to block cars in.
