How to travel to every continent
How I did it: Oceania - April 1993: I am an exchange student in New Zealand at Lincoln University.
North America - March 1997: Spring Break in Mazatlan, Mexico, with one of my best friends Nate Burroughs.
Europe - May 1998: On a trip sponsored in part by Kodak, I am sent to the Cannes Film Festival in France.
Africa - May 1998: On location in Zambia, I was shooting my graduate thesis - a documentary on what it is like to be bi-racial.
South America - July 2002: On my first vacation after starting my post-collegiate career I link up with three old friends from high school to explore South America. Together we tour Chile, Argentina, and Uruguay. I go by myself to Peru to tackle the Inca Trail.
Asia - April 2004: I sign up for the Vodkatrain which is a trip organized for young adults to tour China, Mongolia, and Russia.
Antarctica - February 2005: To complete my visit to the final continent needed (for all seven) I went on an organized trip to Antarctica via Marathon Tours. Antarctica is unbelievable.
