I like to travel light, in fact carry-on, but this this post on Salon is beyond compare. I read with fascination how a couple in the very early days of their relationship decided to travel with no luggage whatsoever for twenty-one days, starting in Istanbul. The absolute essentials included a passport, bank card and, I was relieved to read, deodorant and a toothbrush. The couple had no particular plans, no travel guide and no change of clothes. I suspect you need to have youthful stamina to pull it off but there's no doubt that it is a good test of a potential relationship. They also relied, as Tennessee Williams, in A Streetcar named Desire, put it so eloquently, on the kindness of strangers.
