I guess Cobrizo stayed out in the pasture as he saw the trailer and thought it was for him - he doesn't like to work.
Mom put on Robby's bell boots (until his shoes can be pulled) and he didn't even run around. He went out to the hay bucket and just started munching. Very uneventful. I'm grateful for that! Now he can just be a horse for the winter. He worked hard the past year and has earned it.
