Everything is sacred to these folks. Worse, they cannot tell you what is sacred until you want to do something and then they say it is sacred, unless of course it is to build a casino.
And their sacred holy days, when they ‘need’ to access these sites, seem to align perfectly with the White Man’s holidays.

They are just like the Abo’s in Australia. When the government wants to do something, they ask the Abos where their religious sites are. The Abo response is “tell us where you want to do your thing and we’ll tell you if there is a religious site there”. Needless to say, there is always a “religious site” there.
