    "BTW,
    the official constant for distance to horizon is 1.17 rather than 8/7
    (1.14) but it's a lot easier to calculate using 8/7 (especially in one's
    head)."

    The official constant is only correct in special circumstances anyway.
    There's considerable variability around that number depending on the atmospheric
    temperature profile, so, I agree, go with the one you can calculate quickly
    and remember when needed.

    42.0N 87.7W, or 41.4N 72.1W.
