In January 2001, I flew to Punta Arenas, Chile, on the Strait of Magellan, and worked my way down through the main island of Tierra del Fuego to Ushuaia, Argentina, which lies on the Beagle Channel.  I explored islands with penguins and sea lions, and I learned all about the history of this fascinating area.  The flight from Santiago, Chile, to Punta Arenas took four hours! And when I got to Ushuaia, I was literally at the bottom of the world, only fifty miles or so from the dreaded Cape Horn.
