He was on the horse in less than 2 hrs. (I say "on" instead of ride because although the horse took some steps back and forth around the pen, I don't necessarily consider that a ride.) Today he did an extra follow up on the colt and he did some more ground work and then was able to get in the saddle and actually ride around the pen. The colt took everything real well and in stride.
This morning I got to see him do some work on an older horse. He showed side stepping/passing, rollbacks, how to get a good, solid, stop. I enjoyed this session almost as much as the colt starting one.
Here is the picture of Ken and I. Unfortunately, he chose that moment to blink. Oh well. I had an amazing time...and I couldn't be happier.
