Just curious, what do any of you guys normally use as a carryon when you travel. Last week I went to SNA and back with a briefcase. It worked, had some homework and an exam to study for and I guess looked nice since I was fortunate enough to be placed in first. Would it be suitable to take a backpack with me if I were aiming for F/C? I'd like to hit DC this week and visiting a friend in Brookly too, and backpack would be more handy than a briefcase. Thanks for the insight.
