When I first looked intently at harnessed mules and horses and longed to understand how the system worked, it was the harness that confused me even more than the anatomy and movements of the animals, even more than the overall system. I saw a tangled basket of straps, chains, ropes, all seeming to have purpose. Yes, there were some diagrams in dusty libraries and old books and these did offer basic explanation of the structural design of some harness varieties. But those didn’t help me to understand in a truly useful way. It would be a few years before I would have my own first team and a pile of old harness to figure out. The little bit of book learning and diagram scanning I did failed to educate me. I have told the story before of how my innocence and arrogance got me into big trouble the first time I harnessed and tried to drive a team. Some of that tragedy came from the harness being put on all wrong, making it unable to function properly. That does not need to be the case with newcomers today.
