Thanks! This article combined with Gilles Kohl's article definitely gave me a jump start on getting reverse geocoding going. I combined the two approaches and added some additional features (making it behave a little like a heuristic search algorithm and trying to make sure we spend our time as well as possible). One *duh* moment I had that can save anyone time that thinks as slow as I do: make sure your map is zoomed in to the right level of detail! MapPoint gives you a lot better results when you do .
