    Re: Timed Noon sights for position

    Yes, it overcomes most objections, although the procedure is fairly
    inaccurate, up to about 100 miles, compared to time shots a few hours
    before and maybe after noon.  But Doug is saying that's better than
    nothing.  Also, Doug appears to be using a different procedure in his
    detailed posting.
