MY point is that there is nowhere on this earth where there could be no other person. I Have hunted the most remote areas in Canada and the U.S. If I am there, there could sure be someone else there as well. I don't have an answer for how far down the ridge is far enough or to far. The question was skyline shots, and thats a NO BRAINER You don't take skyline shots. It a damn poor habit to get into or to teach another maybe younger hunter. I don't by for one second that there is a circumstance brought on by lack of oppertunities or anything else that warratns skyline shots. If you try it and the rare case happens and you kill another hunter or bystander, you have ruined your life and lord knows how many others. Tell me, What would make that worth the doing? A trophy? A filled tag? A notch on your gun stock? I think nothing. There are just not a lot of things that just should never be done but this is one of them. I shudder to think that every hunter does not feel the same way.
