I’m writing this article on a flight to Raleigh-Durham; I began it last week on a train from New York City, and added a few paragraphs a couple days later on a flight to San Francisco.

Even in an era of video conferencing, face-to-face meetings are still an irreplaceable business tool, and many professionals (like me) spend a majority of our time on the road.
