Casey IL. ( I -70 ) then south on rt.49 | The amish use fiber glass post 3" round or 3" square. They put 5 stands of high tensile barb wire. They fasten it by using self taping screws and wrapping furnace metal around the strand of wire. The fence goes up fast and is strong. I use high tensile barb and it will turn young calves. 11" off ground and 10" apart up to 5 strands. |
