It was on Private land I guess. Honestly, I have never had much trouble getting permission for Turkeys. Most of the farmers are not real protective of them, many would just as soon have a bunch of them shot....
The Snow is high enough (even though it keeps getting deeper) that you should be able to get on plenty of public ground and find some birds.
I would look first at the public ground that is surounded by private (state sections) , then the low elevation FS ground... some of that stuff has funny boundaries that come right down to the rivers and whatnot. Anything within 10 miles of Kooskia should have birds galore. Heck, without looking real hard I saw 6 or more Toms Stutting at 10:00 in the morning just driving down the road near there last week.
