    When I was fortunate enough to find NavList (much to their dismay)
    "GPS" was roughly in the same category as four-letter words. At the risk
    of being "One-note" Bill, try the NA for rise and set--your one-stop
    shopping source. Sun (3-day average) and moon rise and set are listed in
    the daily pages. Adjust for known or AP latitude and/or longitude from
    Greenwich with the tables on page xxxii and approximate the midpoint,
    
    I understand it is traditional, and a book store is akin to a tree
    cemetery. (However a book can be recycled, if any of the
    discussion-group members ever parted with their collections of
    20-year-old plus NAs  :-)
    
    On the upside, fewer electrons, mother boards, graphics cards, hard
    drives, displays, modems or routers are harmed in the dissemination of
    the information. (Hopefully the NA is now printed on recycled paper with
    soy ink on a hand-cranked letterpress.)
