I may be totally off here, but as far as riding skill level, I think its how you handle the problems that happen, be it a missed jump, buck, spook, barn sour, or one of the many things that happen while riding, so I guess I am talking about not showing, but being able to ride and handle a horse no matter what breed or show style.... I personaly think if you have never been thrown, your green.....you have not pushed your limits !!! I have pushed lots of limits !! LOL
Never approach a bull from the front, a horse from the rear, or a fool from any direction.!!!
