I had not considered Oregon but if they are spending themselves into a problem then that's not where I want to be.
I actually like Colorado, particularly the Frasier valley but the airport is kind of far and medical services are as well. I have been to Bozeman Montana, I like it but it is hard to get to and I can;t recall seeing a major hospital, it's pretty rural. Missoula might be worth considering. Costa Rica is right out for me. We actually like winter.
