haha, we had a 6month old weanling clear our 4ft parrock fence, running up a hill to get to it!! It was my horses half sister, and man did i want to buy her!! Tipped the top rail with her hind feet and skinned her knees a little on the landing but all I could do was stand and stare!!! Until my wonderful betterhalf interrupted my Grand Prix thoughts to ask me if I was gonna go catch the horse or just stand there. ;o)
