Bob,
Don't EVER apologize!! Although there are still a few folks who believe that the world is flat, an intelligent and growing few of us know that it is round. My old buddy Chris Columbus convinced me of THAT. Of course, Chris was considered demented in that he was a "turner". I remember helping him "turn" the masts on the old "Santa Maria". I don't recall who did the "Nina" and "Pinta". It's been a while and my memory is starting to fade a bit.
