I admit I was surprised by the negative reaction to that post. I’ve Seen Some Things as a ring steward and didn’t think that post was necessarily unfounded! If you aren’t super experienced with busy show warm ups, it’s really unnerving. It’s worse in the lower levels IMO, as the classes are fuller and there’s less collective control.
For what it’s worth my last dressage warm up was chaos. There were about 25(!) horses in a large warm up ring (GMHA, for those who wondered). Then there were probably 10 riders who Refused To Give Way not matter what and rode – quite brazenly and at speed – into other rider’s bubbles. I had two competitors nearly collide with me at the canter while I was walking. I believe people who say that warm ups can be jarring.
My non-horsey SO was watching and after my warm up he asked me if we were competing in Horse Bumper Cars.
I didn’t follow the mean girls comment, but I will say one thing. Some riders are absolute jerks in the warm up. Sayin’ that with boots on the ground.
