I saw a product advertized on one of the outdoor shows that I want. It was a step that snapped onto the steel fence posts that support barbed wire fences. You put a couple of these steps on the post, climbed over and then snapped them off to continue your way. I can't find any information anywhere about this product. I know I didn't make it up. Does anyone know what they are called, who makes them, or where they can be purchased? Any help is appreciated.
