My ex-wife and I were 2 of the 12 people at the ranch at the time and helped them move.
It sucks that they kicked Kurt and Elena off the ranch, but there is more to the story.
At the time, Kurt was building casitas for people to stay in, and part of the original deal was that he was to have a tent-camping only setup, so as not to compete with the other brothers existing set-up. Not a good move, especially considering that since it is in fact federal land, he could stake no right to any claims on the land. Also, his agreement was not written, also not a good move, leaving him little recompense.
Kurt has a swagger that could easily rub the locals the wrong way, and the situation between the brothers and him was marginal at best. It seems that he made assumptions about the "american" way of doing things that didn't necessarily reflect the attitude of the local people. Plus, being a hot-headed gringo exacerbated the situation.
