    Strikes me that given the introduction to the list by our host, that would
    be fair game.  By now roads and signs could easily be considered
    "traditional", especially on your side of the pond. If they are invisible,
    better yet. Lewis and Clark, which has been a topic as I recall, did a lot
    of bushwhacking. Nobody HAS to respond.
    When I opted in, I received the following message from our gracious host.
                " <>
    Navigation-L is a list primarily dedicated to the study and discussion of
    all methods and techniques of the art of non-electronic navigation. Our
    aim is to practice and study the traditional navigation techniques.
    All topics involving non-electronic navigation are acceptable. Notices
    about electronic navigation are acceptable, but prolonged discussions
    should be taken off line. The list is open to all levels of navigation
    knowledge from beginners to experts. We hope that you participate in the
    discussions on Navigation-L."
    Cel nav and its history, especially on the water, just happens to be a hot
    topic on the list.  A consensus of the participants if you will.

    How interesting.  I do that without even thinking about it.  Thank you for
    the reminder of something I take for granted--eyesight and experience.  I am
    sincere about that.
    In the final analysis, I must agree with you about off topic, but for
    another reason. Noting the perceived color of the water and wave action to
    determine depth uses a sophisticated computer.  The same computer that uses
    two sensors to determine short-range distance.  Or, having been programmed
    with the distance between a lighthouse and another object on the way out,
    approximates distance off and course on the way in by calculating the
    relationship and angles between the two.  That same computer use
    rate-of-return of a sound wave bounced off a cliff to determine distance
    off. That computer uses electricity.  That computer is between my ears. Do
    you propose to ban that?
    Trevor, any below-the-belt shot you want to take is well deserved. 
    PS. I use two techniques with any list with heady content. If the subject
    matter is of interest I read or quickly scan it. If not interested, hit
    "delete."  If it is of possible interest and I have no time, appropriate
    tools, or current ability (lunars for example) I drop them into a "to
    ponder" directory so I have a breadcrumb trail to follow in the archives at
    my leisure. A list is not limited to MY current interests or abilities.  "It
    is well to remember that the entire universe, with one trifling exception,
    is composed of others."--John Andrew Holmes..
    PPS.  If Frank or George or Herbert or Alex et al posted the same question I
    posted, verbatim, it would most likely become a long-running thread for
    them. I would be lucky to get an off-list response;-)  Or it becomes a a
    jumping off point for a long running thread that never answers this newbie's
    ID 10-T question.  And that is just the way it works, like it or not.
    Pax vobiscum
