I'm OK with domestic and farm animals; up to a point. Plenty happy to armchair wrangle buffalo. Somewhere on the net, a pic circulates of Teddy Roosevelt riding one. No, thanks.

Missouri is where US Army sourced nearly all their mules; met descendants of the biggest family involved. The stories they share; a bit less intimidating; but hordes of those at a time. It was the source of "Stubborn as a Missouri mule", no question. They also disclose best horse they ever had, was the right mule.
