What emergency food staple should be carried in all automobiles?

I say water and trail mix, maybe Gatorade.

Usually for any drive more than an hour I have a “Sack O’ Snax” that i bring; tail mix, granola bars (and of course, the World’s Most Perfect Food…M&Ms) and a couple of bottles of water. Spending years road-tripping with a child taught me a few things…

Good answers. wife and i have discovered that a box of Rirz Crackers and a gallon of spring water suffices for us. we have used this combination on two separate occasions, while waiting.

A .50 cal ammo can filled with almonds, bottled water, a few peanut butter containers from the breakfast buffet, plastic utensils, 2 pack of tissues, a pair of underwear and socks in a freezer bag, 2 packs of matches in a sealed bag, an old Leatherman, and a pencil and notebook.
Oh! And two Orion Skyblazer Red Aerial Flare/Launchers.
The box is always ready.

Car-boyhdrates! Keeps your engine running, although may give you gas :¬)

Cashew nuts. Very filling.

Ranch dressing. Goes with everything.

I always keep a small bag of peanuts with me. Hopefully I never get stranded with someone who’s allergic to nuts…
