In late August of 2010 Rolf embarked on a trip that took him around the world without using a single piece of luggage. For six weeks he explored 12 countries on five continents, crossing the equator four times, without carrying so much as a man-purse. The few items he did bring (including a toothbrush, an iPod, and a few extra items of clothing) were tucked away in his pockets. For a real-time account of the adventure, including blog essays and two dozen field-produced videos, check out the No Baggage Challenge blog.
