Cattle don't really bother the elk from my experience. While annoying, especially if you are tenting it and cow pies and cattle all over the place in the middle of the night kinda sucks, but the elk aren't really bothered by them.
it is frustrating the DOW leases out areas for hunting and pays money from our license fees for these spots only to have cattle and logging and other operations going during hunting season. But at the same time at least it is public access that would otherwise be private hunting only and only leased by an individual or permission only.
