I understand how you feel but unless you are 6'6" and weigh 350lbs, those horses need to stay back or you could get hurt seriously, just from them moving out of another's way.
Oh I totally agree with you. Knock on wood, I've never been hurt handling a horse. (Riding them is another story) The whole ordeal only lasted about 5 minutes, but 5 minutes is enough. Usually I'm pretty crafty about sneaking horses out of there. :-) This time I couldn't get out before I was noticed. This sort of thing doesn't happen all the time, thank goodness.
