Sweat

I found a business card for a horse trainer at Tractor Supply. I called him today. I told him the story of Buddy, Zum and the ranch saddle accident. This trainer said it sounds like all Zum needs is an experienced rider who is not afraid of Zum to ride Zum on the trails 8 hours a week. This trainer said Zum needs to sweat on the trails. So where am I going to get this rider?
