The travel bug sank its teeth into me the summer I turned 25 -- leaving me with an uncomfortable, out-of-reach itch I just couldn't scratch. I didn't grow up in an upper-middle-class family that vacationed in Europe. I'm an immigrant from Jamaica who moved to the U.S. when I was 16 and stayed put. The American dream had been my adventure. But when I got a passport after becoming a naturalized citizen, it sparked a desire in me that I never expected.
