I long to be one of those people who packs a healthy, well-balanced meal when they travel. I have friends who pack lunches for their plane journeys — thinking out which foods will complement others and how it will affect the way they feel mid-flight. I don't do this. Usually I can barely manage to eat a decent breakfast before I get out the door. But what I can do is throw together a trail mix for those flights — one that's been put to the test during quick camping trips, day hikes or longer car rides. And I'm always thankful that I took the few minutes to do so.
