Never seen one in person but from the pic Porter looks to be a mighty beast that could get through most any fence if he set his mind to itUM some area's are 4 or 5 strand barbed wire, some areas are sucker rod attached to railroad ties, and some are the 16 ft cattle panels attached to railroad ties every 8 feet with top and bottom 2.8 boards. OH and tried the yearlings on electric fence last fall.
ALL work. Quite well.
