Usually in the ranch horse classes, and it depends on the association, they will actually ask for a sliding stop. So if the pattern asks for just a stop, you do not have to do a sliding stop.
They also ask for the huge distance off the wall because a ranch horse shouldn't need to be guided by following a fence/arena wall.
Just a note, some ranch horse shows I have been to didn't use the arena, but just set up cones in a open field to simulate more of a open area. If you have questions, don't hesitate to contact the association and I have talked/asked the judges questions before a show.
You better take video! I'm too far away to come watch otherwise WS could hold your hair, I would hold the bucket and then we would drink a LOT of Molson and be your cheering section...LOL!
I DON'T LEAD 'EM AND FEED 'EM, I RIDE 'EM AND SLIDE 'EM.
