update (via pda): walked on glaciers. kayaked in bellingshausen sea. returned
safely from antarctic peninsula via boat. traveled from tierra del-freaking-fuego
to buenos aires via badly signed airports that announce only in spanish. got to
b.a. airport despite mistake on part of transfer bus from hotel to airport. even
survived customs in miami. and now on the very last leg we're stuck in chicago
because of a little snow. yeesh.
