Good points by everyone.
It takes a lot of sand to hang where you are not welcome, especially if you fight. One of the reasons I left Idaho. I couldn't take it anymore. (I also missed the high plains/short grass prairie).
I think of the small businessperson who supports "our" cause, left twisting in the breeze because of a Utah boycott. They go tits-up and leave too. I think maybe if there are no resident folks on our side, then "we" are effectively ceding the floor to the opposition. But I also think "our" money eventually ends up in "their" hands if we go there (taxes, etc.).
I don't know the answer but I do love their land, especially the slick rock country.
One thing I would like to see is for the "big tent" we've been talking about to come up with a logo. It could be put in business windows, bumper stickers, etc. We could try to funnel our money to these folks. Hell, there could be version of it with a red diagonal line through it for the PLT types to post in their windows. That way money could vote (we all know it does anyway).
If boycott is the option, there needs to be an effective means of protecting *our* public lands while we are absent.
