I know this reply will be too late but for future reference unit 11A is very restricted on public access. There are a handful of small state and BLM land parcels along the clearwater river which tend to be very steep. I imagine it would be possible though to find some mulies in some of them. I live in the area so if you need any help in the future regarding that area just PM me.
Did you end up having any luck with that tag?
