One of my neighbors is a retired airline pilot and has his own Cessna. He was taking local newspaper journalist up to take pictures of a Vietnam memorial. They flew 500ft over the lake I was sailing on. Not only was I the only sailboat, but I was the only boat. The gal didn't take one picture!! I thought recognised the plane and bumbed into the neighbor a couple days later when he told me his passenger had a camera, but she wasn't much of a small plane person and was a little airsick. I was so bummed.
