Antarctica
We had an absolutely amazing trip to Antarctica. We took several days to get down and back through South America, then we flew into King George Island and got onto a boat for a week where we saw iceburgs, penguins and a solitude that is rarely experienced anywhere else. Our fellow passengers were like minded travelers that made the trip even more enjoyable. We would spend time with any of them any other time we get the opportunity. For two people who are more or less introverts, this trip was our most sociable and most enjoyable trip ever.
