While i admire Alex's achievement, for me reality of family expectations prevented my going too far out, which was my original intent six years ago when i left Sydney. Many of us have to compromise on our dream location to be able to get to the hospital to see our new grand child, or have access to a doctor, drive a couple of hours to see family or lunch with old friends, or simply to be able to get to a Bunnings once in a while. There are many areas two hours outside of the major cities that still offer dark skies, services and facilities, that do not cost a fortune. Going deep bush is a big transition, but easing out a couple of hours is a good compromise, that is often supported by family concerned about aging parent welfare.
and you can still have your observatory.
