That's very good advice. It's also a good idea to take along a piece of rope jic... last time I went out for a long trail ride, one of the girls had the same kind of headstall you had; the leather was worn and broke off at the snap. We managed to find a small piece of rope and wound it through the holes for the ride home, but especially for such a large group of riders, we were very ill prepared. Shame on me. I know better.
Last year, the stirrup leathers on my son's saddle broke off. Would have been OK if it was me, but he couldn't handle it. Had to walk the horse back.
