The larger point is that there's more to life, more to consider than rocketry and astronomy. I'm not trying to put down those things' importance. Just remember not only the actual climate, but also the cultural and political climates. Are things like concerts, theater, sports, and other stuff important to you at all? The ability to find new and interesting foods other than barbeque and Mexican? You have all that now, so think about what you might miss, as it will help inform how far out into the boonies you want to be, and which cities you want to be your nearest. What sorts of laws and government programs would you like to live under or want to avoid. (Both halves of that question apply to both/all political leanings.)
I don't have any suggestions of a location for you. Reading your first post, I did think of New Mezona and Colorado, but I know virtually nothing about them. For what it's worth, where I am I have dark skies and a good rocket club, but you've "been here done that" about the weather.
