Ahh....yes, ATLANTIC instead of SEA. Makes more sense.
Amazingly, we just found out that our neighbors (just one house away) are in Iceland right now! I cannot believe it and I look forward to their return to hear some of their stories.
I have had a number of ideas about puzzles for this forum, including this Up and Down style. Sadly, I have limited time to work on them. Besides that, I am generally the only one who tries to solve them. This past puzzle is another example of how little interest there is for puzzles on this forum. Thanks for your comments, ta0, and responding to this puzzle.
