Gentlemen:
To further the highjacking of this thread - or perhaps bring it right back on topic with a truly authentic conveyance - thought I'd post this scan of the late Roger Beierbach and his daughter Eve, with their six mule hitch (Zelda & Casey, Chum & Charlie and Randy & Brady) during a trail drive a few years ago.
Roger Beierbach was a southwestern Saskatchewan rancher who did as much of work on his ranch with horses and mules as he possibly could. A few years ago, he was caught out on the open prairie in a sudden thunderstorm, and both he and his horse were killed by a bolt of lightning. His widow Heather, and his children, continue the ranch operation as he did, and each year since then, Heather (who is quite a talented photographer) has published "The Slippery Moon Ranch Calendar", commemorating Roger and featuring her photographs of ranch work and play - always with only humans and livestock in view - never any modern vehicles (though you realize they must be there somewhere, out of the range of the camera lens ....
This is one of those photographs:
