Just build the wall on the American side of the Res.
From my Post 11: “Regarding the reservation being split. . .these drunk and druggie indians are not prohibited from traveling freely on both sides of the fence, AND they can cross the fence easily as they have gates on the fence that they can open and close as they wander unimpeded back and forth between meh-he-co and the US.”
“Just build the wall on the American side of the Res.”
Exactly, my thought also.
