Good questions that are not easy to answer at least for me. I am very fortunate in that I have traveled much of the world and have been on almost every continent. I've always said that there is no place like the US and certainly no where else I would rather life due mostly to the freedoms and rights we have under the constitution and bill of rights, but the events of late now has me rethinking this. The problem is that there is no where else in the world that I could have the type and quality of life I have now (2 40x60 shops, lots of firearms, 100m range on site, etc.) so this would mean a very drastic change which I am not sure I could deal with very well for very long.
I've been all over the US and have to say that geographically I really like western WA but the politics here are getting crappy. I lived in Monterey CA for a year, beautiful place but again, the politics SUCK. Spent a lot of time in NC but I have no desire to live there again.
As for the world, I have seen a lot of cool places, Israel was nice, Norway was beautiful but again there isn't anywhere outside the US where I could really thrive I don't think. That said, much of my adult life was spent in Asia so that is where I would probably head, specifically the Philippines since I speak the language, my wife is from there and I have spent a lot of time there.
