Thanks for the idea, i think i will hammer a part of the load of old horseshoes my brother (a blacksmith) dumps in the scrapbin undr my workbench on the fenceposts and see how the horses like them...
I dont like my old man's way of ropes and wires anyways...
Horses are smart yes, but if you tighten that bolt on the pole enough so the horseshoe turns with some friction, the horses wont keep trying that long..
