If you have never known the delight of journal-keeping, give it a try on your road trip. Every night, before you go to sleep, record the happenings of the day. A paragraph is enough, or a few words, if that's all you can manage. Your photographs will be lovely mementos, but they can't reveal what's behind your smile. Photographs record solitary moments.
Words can record the journey.
Those are our top ten, Adventurers, and we wish you the best of times when you set tire to pavement this summer.
