 The Teton Sioux near South Dakota, they call it the Bad River, would have been where they most almost came to blows with them. And it was basically over the Sioux wanting to kind of charge a toll for them to continue up the river. And where was the most affinity and helpfulness would probably be the Nez Perce, because they could have wiped them out, and they didn't. And the Mandan, too, helped them a lot.
