i know almost nothing about horses, but i do know they have 4 natural 'gates', walking, cantoring, galloping and (trot)???

and your post seems to imply that the tennessee walking horse has almost a fifth- natural gait.
I'll wait out the week, if you are going to cover gaits later...but if not, i will have increased my knowledge of horses!

--as an aside, why do we race horses, but when we gamble, we play the ponies?
