I can see where Morgan people would see Saddlebreds as nuts and vice versa. They are two different types of "hot". Saddlebred people are used to this type, while morgans are of another type. I am -a Saddlebred girl and don't like Arab-hot. I just don't know it and we don't mesh. I don't like TB-hot. I ride the ultimate TB product. The raw form is a little too hot for me.
I have a little Morgan mare friend. She is a GAME sister! Sweet as can be, but snorty, flighty, and as game as any Saddlebred I have met! I'd almost call her nuts, but she just has a motor.
