I think I'd go for a PBY-6A. You can fly to your favorite Caribbean port,
set down, launch your dinghy and go fishin'. Not to mention all the lakes
in Canada and Alaska.
I think I'm with Charles. Go to all the lakes or oceans you want. Just tie up to any dock to live. Uh oh, storm coming, lets go! Get to see all the hot spots and invisible spots, air travel, sea travel (minus the karaoke). What more could you want?!
