I had two apple trees in Rock Springs, which was a zone 2-3 area. I believe if you settle somewhere East of the rocky mountains your zones will get warmer and so your choices of fruit and nuts will improve. I advise people to ask other gardeners, in the area where they are looking to settle, stop at the local nurseries, and look around in the towns at what types of trees are already growing in the area.You can also improve your chances by improving the microclimates. Use windbreaks filled with very hardy trees to protect the more tender ones. Rock walls or mulches soak up the heat during the day and release it at night. ETC.
Biathelon has a great idea. People are always looking for fresh garden goods. And real organic stuff comands a premium price. I have heard that many restaurants will buy garden produce also. I spent 4 years living in the bedroom communities of Aspen ,and I assume Jackson hole would be the same, in that there were many people who sold thier organic goods, and arts and crafts to the "rich folks" and were making good livings at it. Beautiful ,handmade quilts are in ar class by themselves and I think if you let people know you have them for sale you will be able to sell them! Hope this helps, Miles
