    I agree the average of +175 and -175 is 180, but the average of +5 and -5
    is not 180!  Since we're dealing with the globe, we have two diametrically
    opposite average points!
    
    Sorry, Maui did sound great...
    
    Thinking a bit more on the problem, of the 14 respondents, 9 are in the
    western hemisphere and 5 are in the eastern.  Remember learning to plot a
    run of sights to throw out ones which are obviously off?  Hmmm, if we throw
    out the five in the eastern hemisphere (obviously off!) we probably have an
    average longitude around Salem Massachusetts (on the order of 69W, if
    memory serves me).  OK, folks, relax -- I'm JOKING!
