The final step of getting to Antarctica was taken care of today. Chris booked our tickets from Pittsburgh to Miami (from there we hop on a plane to Buenos Aires and then to Ushuaia). He got an awesome price and very kindly used some of his frequent flier miles to get us upgraded seats. I am sure that will be especially appreciated on the return trip home after lots of travelling.  All that's left to do is train and show up! March 2nd (departure date) is going to come quickly!
