I know the kids in the first video.. It's the Georgia 4-H state show held in Perry every year. My sister shows there each year, even though she shows in the running she also shows pleasure occasionally. They are not the best horses and the ones you're seeing are the horses that aren't ridden by a trainer much, but by the kids. The horse cannot be ridden by siblings and can only the the kid's horse, no exceptions. Our 4-H state show is all about the kid and their horse, not how much money and training is put into it.
