My Uncle Pete used two plow horses, Prince & Joe for his truck farm. I grew up riding them until 1957 when I left the farm. That could be why I am still bow legged to this day as plow horses were very broad in the back and strong as well.
Because of that I rode every ornery horse that nobody else could ride and got pretty good at bronc busting.
Then I got smart and gave that up.
