What a funny expression! This is our mare Ebony's confused look when her pasture mate escaped their pen and she did not! We use electric tape and temporary posts to easily contain horses and rotate pastures. Being able to change our fencing configurations without hauling heavy panels has been very handy to our farm management. As long as the fence is kept hot, out horses never challenge the step-in posts and one strand of tape. (This escape was caused by a clever mare figuring out when the fence was turned off, then jumping a low spot!)
