text: I don't even remember why I said "offices" in that note.  I meant "commercial area", and by that I meant the practice of simply marking an entire downtown area and labelling it a commercial area.  "Commercial area" should mean something like a shopping center, not just an area of town.  Same for "residential area" -- it shouldn't mean just a part of the world with houses in it, it should mean a designated neighborhood or housing development.  And "wood" should be a designated (named) area, not just any spot with a few trees.
