All we have to offer is land and refuge and access to more legal wild food than anywhere else on earth, and a community of people with place-based skills and knowledge.
There's a thread somewhere about our rationale for selecting Alaska as our first collection of nodes, but it could probably use a fresh articulation since that decisions was made about a year ago. In short, our priorities are wildness and wild food.
The only negative I've experienced with our chosen location is the automatic, "it's too cold" reaction. On one hand, that hints at a misunderstanding of the ecological diversity of Alaska (spans USDA zones 1-7). It's also often a reflection of the domestication we all share. Unfortunately, pointing that out verbally seldom leads to a deep enough level of understanding to feel what casting aside assumptions about humans and temperature variation can mean.
