My parents were dealers and I recall us going to Kentucky Horse park in the late 80's... I would have been 6 or 7 but I don't know why else we would have went unless Wheel Horse was putting on an event there. I'll check with my dad and see if it was Wheel Horse related. I don't recall seeing any tractors that day but with all of the large horses and things, tractors being a daily occurrence in my life, I may have not noticed them. Most of our vacations and trips back then revolved around Wheel Horse events so I think it's highly likely.
