Out of a dozen major relocations throughout the country, only two were back to a previous city. One was dictated by the Navy, so there wasn't any choice in the matter. For the second, my wife and I chose to return to a city we previous lived in for job-related reasons. This latter case only stuck for about 18 months before we moved again to someplace new. When we retire in the near future, it's to yet another new location. Happy feet.
