Wow, that is really cool. I can tell that you and Chance do have a very trusting relationship. He looks really relaxed. I LOVE that unique way of mounting. And I have NEVER seen anyone dismount off the neck. Very cool. I don't need to tell you to be careful though, I'm sure you know the potential risks. I can tell that you are trying to be careful by your methodical movements.
Keep up the great work! I can see that you are having fun.
