Thanks for the replies fellas. Just got back from a couple week vacation in MT with the family.
@Birdguy, thank you and sounds good. From looking at maps, it seems there is a good mix (50/50?) of public and private in that unit. Should be interesting to see what I find when I get my eyes on it.
@Onewhohikes, No, I have never been in the unit before. Will be making a trip soon. I am not looking for anybody's honeyhole. If you are that generous, please just pm me so that we don't blow up somebodies spot for all to see

haha
@Wingin it, I have no experience with rattling, but I was planning on bringing my grunt tube for sure. What are your thoughts on that?
