I have done a lot of work over the years on many reservations in Minnesota, ND and SD. They are all schlitzholes.
I have also worked on many public housing projects in Minneapolis and St. Paul. By far, the reservations are much worse. I could tell stories for hours about what a nasty place they are.
If you leave any product on a site it will be a pile of ashes by the morning.
Plow them all down and make the people assimilate or starve. Their choice.
