Travel Snack Box

Do you carry a travel snack box in your vehicle? If your family had to spend several hours sitting in your vehicle waiting for a tow, what would you munch?
Our travel snack box is never full of the same munchies twice, although I can say there are some staples I try to keep in it. Favorite must-haves are raisins, figs, dates, nuts and homemade yogurt chips.
