DS.....I'll leave the BS calling to other folks, but if you're having trouble lead rope educating a horse, he'll also give you trouble on a picket. Some of the old timers, especially when they have several horses to work with, will use an 18 - 20 foot long log about 12-14" in diameter and tie one end of a 20 to 30 foot rope to the log (be sure it is smooth) and the other end through the halter ring and around the horses neck. A couple days of dragging this log around and fighting it and it yanking his head down will graduate a horse in a hurry. I know to some this seems cruel, but it is effective, but be sure to use a soft rope about 5/8"
