Name any drug you want and I will tell you that traveling is more addictive. Imagine being completely exhausted in the French Quarter of New Orleans, or New York City's East Village, or the El Pueblo area of Los Angeles and your addiction is whispering in your ear, "just go one more block and see what's there." Just walk one more block. Just take the long way back to the hotel. Just cut through the park. The monkey on my back is real and people who have never traveled don't understand. It's beyond the annual vacation. Because of my job, I travel for work and that feeds the addiction. I may be in Portland on Monday and Miami of Friday. Though it's largely not glamorous, it is a slightly more comfortable form of vagabonding. I won't say it's comfortable, just more comfortable than being a hobo riding the rails.
