Sorry about your loss, that’s rough.Sounds awesome! Brings back memories... My Dh#1 and I joined a little religious group traveling through Manzanola, CO in 1974, and they had a unicorn hitch. Traveler was the lead horse, an American Saddlebred if memory serves. King and Mr Ed were the wheel horses. I learned not only to drive that team, at age 21, but to harness them as well. We travelled through five states before I suffered a miscarriage and became too ill to travel, ending up in Hamilton, MT. What an experience!
But glad you enjoyed the horses and learnt to drive them - a unicorn hitch can be tough to learn to drive!
