Granola bar

From Trail-Finder -- Dedicated to getting you outside

What GORP lacks is variety, so granola bars stepped in to fill the gap. Available in both crunchy and chewy, they're cheap, easy to toss into a pack or pocket, and come in a variety of flavors. You can buy them mass-produced, and they'll last a year or so, or can make them yourself, which is both healthier and cheaper, but they don't last long.
