So in all those green classes the horses are not actually green? Hmm. Who knew.
I am betting that AQHA was not sitting around coming up with ideas to give “culls” from WP a chance to compete. My money is on people got fed up and said, hey, there’s more fun to be had with these horses, let’s approach AQHA to see if they’d be interested in letting some of us take our horses back to their actual roots because we’ve seen this stuff can be fun.
It’s a different interest, just as Working Equitation is - fun, different and does not rely on “culls” from any other sport.
