Well, Neil, now that you mention it -- Nancy and I are looking forward to the time when the big US cities become unlivable because of heat and drought and places like Texas and Arizona become real (not just virtual) deserts. We figure that the UP will become a more "temperate" area with global warming happening, and with that -- scads of people will move up here from down below. They'll all want housing - room on which to live. What we've done is bought the land on which our house rests -- 60 acres of land. We figure that although we'll be dead a few years before it's needed, the land can be held and sold or developed by our heirs. Heck, on 60 acres you can have thousands of resident (see Tokyo, Singapore, Mumbai, and so on). Our kids and grandkids and so on will be wealthy land owners. How's that for foresight -- taking care of the offspring? Some day they'll thank us.
