Vista, dude. But otherwise right on. And there have been times I was wearing the conference speaker shirt (non subtle - name of conference, year, word SPEAKER) and carrying the conference bag, and literally the people ahead of me were carrying the same damn bag, and I got asked to justify the business aspect of my trip.

CBSAGuy, I was really asking, not snarking. I like to look for the positive in my life. If I can react when asked "Why would that be a business trip?" to think "they are just flagging my no-purchases" I will be happier than if I think "they don't believe I belong at a tech conference, how dare they ask me to prove my technical competence while lined up at the airport, and besides, it DOESN'T EVEN MATTER if it was business or vacation anyway, grrrr grrrr grrr...". So if you can clarify for me why an agent might sometimes drill in a little in response to the "why were you there?" question, I would appreciate it.
