The long flap is a defining trait of a dressage saddle. When riding dressage, you generally ride with a longer stirrup to lengthen your leg against the horse.
My cousin rode well in the show. Cinnamon isn't always cooperative, but she makes him listen. Her parents brought up how it's my fault that my cousin rides. It's true! I took her to the barn with me years ago and put her on a horse. That was it. Once the equestrian bug bit, it never went away.
I'm proud of my cousin, for how she rides and for how she takes care of her horse, all by herself. She works hard to be able to keep him, and she works hard making him the horse that he is. He has come a long way with all the effort she has put into him. I see a dramatic difference from when she first got him.
Sure I'm biased, but I think anyone can enjoy going to a horse show, even if you can't tell if a horse is cantering on its left or right lead. Horses are remarkable animals. You don't have to be able to ride to appreciate their beauty and grace.
