In the pack I have 1 food item usually a rice crispy treat or pack of combos(i can't stomach the gels)and either a GPS if I feel I may get lost or want to print a map later, or a camera for pictures. Not much storage in this pack. I prefer to pack light until something goes wrong of course.

I have to drive to go on a trail so I have all kinds of stuff in the truck which is usually 10 miles or less away.
