Biggest issue here is a couple of people who don't really ride but tend to get in the way of those that do ride.
Yesterday a person on the ground (and a guest of a boarder no less) was trying to get a horse to yield his hind quarters. She was paying no attention and pushed the horse right in front of a boarder. Horse being worked from the ground HAS kicked at other horses in the past. Boarder was very gracious and avoided the situation neatly and without comment. (I saw the whole thing)
Thankfully the whole group in question (boarder with her half dozen guests) is leaving at the end of the month. But it does bring up a good point on who should yield to who.
