This was a bit of a conundrum until I got it; nice to have a different angle (not maths!) for a change ;)
btw. Completely unrelated to photography in a way - but related to art and the human spirit; bridging things enriches life.
Thanks a lot, Don. Funny detail: I ran into the owner and his wife right after this shot (not literally - we kept our distance); he was proud and happy as can be and said it was a really nice ride, too. They still use it often ...
