Is it ever open to hunting?
If you will just Bing or Google it, many links come up telling of the hunting opportunities there....Wiki says hunting, fishing and grazing are still allowed, in most parts.
Some is BLM land which is usually open to the public. We had access to BLM land in Idaho when I lived there, just had to close gates, etc.
That .... Carly Simon tried to block access to Idaho Public Land (back in early 80's) but we took her to court and she had to put gates in her fences.
Guided elk and mule deer hunts pop up too...so it looks promising...like I've told dozens of guys......Google is your friend!
