You heard it.  January, Alaska Drift, ~40F degrees... take a dip.   Be it freeing or mind numbing, a polar plunge should be on every adventurers list of thing to do.  And what a beautiful place to do it.  We won't be embarking onto the Nautilus which is docked just below the surface, but it's there, all observation decks are watching.  I will be there to relive the experience from 50 years ago, we'll see if the grunyuns run away this time.
