Took Mezza along with Boo, (Jennifer's horse) to the local gymkhana to watch the action. This is the second event she's trailered out to watch.
We worked both before trailering out (in the round pen) and again briefly at the gymkhana for a 'refocus'. She was very relaxed again, and I took her out to the middle of the equestrian field and walked her around while everyone was riding, then took her back to the arena to watch. No fuss, no muss. I was impressed.
