What about crowdfunding? Forests and parks are of high public interest and might emotionalize many people ... have a look into my conference paper on the social mechanisms behind crowdfunding ...
Thanks, those are all great ideas. I have actually thought of that. You see Jackson, Wyoming which is just on the other side of the Tetons, which is a very small town, has more millionaires per capita than most places in the US. My colleague and I have actually talked about a fund raiser. They include:
Christy Walton, the richest woman in the world with a net worth of 34 billion dollars! It is from her husband, the Wal-Mart founder Sam Walton. Or Harrison Ford and his wife. There are many others. But I would rather that they contribute out of interest, and not duress.
