Unheard of in my world.
I was much too sheltered growing up, I had no idea there was such a thing as this.
This is a pole bending competition at the Pea Ridge Mule Jump - in the South, as a game, mules are made to run through an obstacle course.
I have finally found a way to use the word "irascible" in a sentence. Mules are irascible.
It is the perfect word to describe them.
I suspect this will turn out to be quite an entertaining event.
