These are shots of a serious fall in a two foot slick creek bottom. I can't say a project mule would handle this fall and just stand up, shake like a wet dog. And frankly I hope we do not have the opportunity to test him, it will be winter here for his training :

Everything going as usual Oh No! No drill tec shoes on Rambler
Look close and you can see him listing to the left
Sometimes accidents happen in slow motion, not this one
Boom and we were down and sucking water
He is trying to stand up, but not panicking
At this point Rambler is flat on his belly and I am standing in my stirrups on the bottom of the creek trying to decide if I want off or just ride it out.
  Well I stayed on. His head has been under the water. Look at his ears. Watch the movie it is a good one.
He is struggling back on his feet.
This not something we practice:) But look how he gets back on his feet. Those are still slick rocks under him

After he is up, he collects himself and walks up on the waterfall as if noting has happened.

Well, guess what, we are going back and try it again:)
