As you quickly learn when you travel with just one bag — for any amount of time — every bit of space matters. As I was packing to move from Costa Rica to Panama, I had one of those moments of celebration… The celebration when you gain a bit of space, when you get to downsize even just a tad. Most of you will laugh at this one. I did. But my finally! grin was ear to ear at the time. The moment? When I finished a pack of dental floss and was able to fit the floss from my bigger container into the smaller one. I know you’ll wonder why I’d I brought two. It was because I had them when I left LA, each was partially used, and I was sure neither would last long. I am seriously amazed how long each lasted.
