I have spent 20 years in the area. Huntnnw is correct and I have come to learn from his posts he spends good time in the general area also.
I have never once seen or heard of it being a tribal issue at all. I can say for a fact I have witnessed first hand the locals poaching. And talking with many of the landowners that I do frequently tribal has never even came up rather a good deal of locals that are habitual poachers to put food on the table. It is a feed the family deal not a thrill kill. Poaching is poaching however this is the type of poaching I know goes on around Colville and to some extent but to as great up north in the Republic area.
