I was trailering two of my horses to a local ride and was
riding with my two back doors open on my small, 2H BP trailer. One of
the horses was a 16.2H big bodied Paint, who not only pooped often, but in
prodigious quantities. He was so large, that his pooping
orafice was higher than the top of the ramp and butt bar. There was a
car so close to the back of the trailer, I couldn't see him in my
mirrors. All of a sudden, he backed way, way off. When we got
to our destination and went to unload the horses, we finally saw why
he backed off. There was a mountain of poop stacked on top of the
butt bar. But it could not have been the entire quantity. This
guy was so close that the horse pooped out the back of the trailer and it
landed (as far as we can tell) on the hood of this car.
