    As I understand it, for our List members who don't live near the open
    water that (and maybe an artificial horizon) are about the only way
    they get to practice their celnav skills.
    But different strokes for different folks... I don't have much more
    than a passing interest in lunars (other than maybe as a curiosity
    factor), but I also have the luxury of living near an ocean so I can
    understand their enthusiasm for working them - just as they also
    tolerate my "realistic" experiences and adventures (and occasional
    foibles) doing celnav practice with a real ocean horizon.
