This list certainly gets points for originality! (I'm going to look up those journals -- I always keep a travel journal on trips - international and domestic, especially camping.)

I keep a moleskin journal and a couple pens in whatever backpack I'm carrying, even on walks in the city, as well as several in the car.

Also have permanently in my passenger door the following paperback books:

Dharma Bums - Jack Kerouac

Travels with Charley - John Steinbeck
