I grew up a long time ago…in the dark ages.
This was the norm for barns. We all acknowledged that riding was dangerous and that was ok.
I rode at a huge academy in a different country, and rode every single horse they got right off the truck. I rode spookers and bolters, one horse tried valiantly to buck me off the entirety of my trail ride. Even my own first horse launched me a fair number of times.
Kids, generally speaking, were known to bounce. The number of times I came off and saw hooves pass my head was many. Thankfully my mom insisted I wear a helmet, but that was before true safe headgear was really a thing.
Anyway, it’s possible that this barn is just still operating off of the old model. There was a time when people weren’t quite as apt to sue.
And honestly? It made me a very good rider. Until I gained 80 lb as an adult, lost fitness, and lost my balance, I could literally ride anything.
I’m not saying that this barn is right, nor that you should willy nilly throw kids on sale barn horses and wish them good luck, but I do think we have lost something with this insistence that horses need to be as quiet as robots before we ride them.
Sometimes it’s the quiet horses that get you too - you become complacent and even they can have a moment because these are 1000 lb animals without a prefrontal cortex who spook first and ask questions later. There are some 5 year old horses I wouldn’t hesitate to put a kid on and some 25 year old horses that I wouldn’t dare do the same with.
