When I was in high school, I wanted to be a nomad. I thought there was no better life than the open road and was going to have to find a way to make that happen. Then for my 17th birthday, my mom, sister and I took a trip to San Francisco. I was incredibly disturbed by all the young homeless people. They were my age or only a little older and their life did not look romantic, it looked rough. This blog from TED is a pretty interesting mix of the two themes of nomadic life: the romance of it and the harsh realities.
