When I was a kid, Don Busse (Daryl's Dad) would pull into a fair with 2 semis packed with horses. They'd throw all the harness in a pile next to the semi. The horses wore different equip from start to start. Don would go into the speed office with a stack of eligibilty papers for pacers, and another for trotters. He'd toss them on the table and say, "Put 'em in where you need 'em." Then he'd check the draw to see how many drivers he was going to have to round up. He'd walk the barn area asking people if they had a USTA license, and if they'd drive for him. Then he'd say, "That's the horse right there, getch some harness out of that pile."
They were all about half broke and wild. He was a Gypsy's Gypsy.
