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. -- GregR --- hch wrote: > > Jim: > > I too apologize for my overly caustic response, however, must state > plainly my exception to the tendency so evident for name calling and > somewhat less than polite innuendo that occurs on this List, > including that which is so frequently exhibited by some of our more > distinguished members.
