Aggie Weighill: Tom's not the only one proud! Great posts and thoughts! I love that you are questioning our "right" as humans to explore, dominate, and ultimate change all environments on the planet. There should be "no go" zone everywhere - the question remains...Does all of antarctica need to be a no go or is it possible to have managed visitation. Of course that leads to questions of elitism and access! Have a great trip and keep the pondering and questioning going!
