I’m not really a fan of rusty railings, others may find interest in them but I dont see their appeal, I just can’t get past the imposition on the land, an electric cow fence might be more aesthetic if crowd control is what your after. But if you intend to keep them away, to bind them, to deny them, then a big rusty fence is what your after.
Visit the stones when ever you can, visting hours are between now and then.
