Theory and practice. Some of us enjoy one more than the other... Rick just happens to be our chief pragmatist on this list. He is only doing his job! ;-) I have learned quite a bit from the discussion myself. I particularly liked the fact that we haven't discussed this topic in the past few years, so it is a nice NEW topic. I am, however, still waiting for George Huxtable's summary of lunars. I still do not have those clear in my mind either! Dan -----Original Message----- From Navigation Mailing List [mailto:NAVIGATION-L@LISTSERV.WEBKAHUNA.COM]On Behalf Of Richard B.
