Update from the Unofficial Crew heading to Antarctica. Today was our first full day in Ushuaia, Argentina and man did we feel the urge to go skiing! We headed up to the Martial Glacier which is located about a 10 minute drive from downtown Ushuaia. When we met up with the van that was to take us up to the mountain it really felt like spring but by the time we got up to the glacier it was full on winter. I have never seen a place where the weather changes as fast and dramatically than it does here on the southern tip of South America.
