Specific to draft animals, horses baffle me. I ask Duane Westrate lots of pretty basic questions and I drove Tillers horses once, pulling a log. I lived to tell the tale, so I figure I'm done.
Headyokes for oxen are like that. I know the idea and I can see the appeal, but you could probably fill a thimble half-full with my expertise in that area.
So, I make no commentary on this video. I just stood over Dale's shoulder and filmed him re-adjusting his off-ox's straps, while he chatted with Thomas Philbrick at the Ingham County Fair this week.
