Was showing at the Paint Horse Reining Futurity on a mare that had some nice parts.  She could circle and turn, good lead changes but not much ability to stop.  We got thru the go round pretty well and made the finals.  The finals pattern was a run in...all the way to the other end, roll back, run back to this end stop and roll back, run past the center.  The arena stands were full of curious on lookers, ready to see a blazing finals.  The gate swung open and I urged my mount into a pretty good run to the other end at the appropriate moment with impeccable timing, said whoa and pulled...nothing happened.  With the wall approaching I decided to ask her to roll back anyway, which she did beautifully.  We ran to the other end and tried to stop again...still nothing but once again we performed a roll back without  stopping .  As I mentioned she was a gifted turner.  I eased up quite a bit for the middle stop, which was more like a skipping stone on the pond.  She did circle and spin well and the last stop was exactly like the middle, skipping and leaving no sign of a slide.  I'm certain not even a bloodhound could have found tracks after her run.  We ended up second.
