40. GORP
Trail mix: fueling hikers across the United States.
"Good Old Raisins and Peanuts," GORP is the energy salvation of backpackers everywhere.
Centuries before trail mix came by the bag and the bin, it was eaten in Europe, where hiking is practically a national pastime.
The thing to remember here is that the stuff is American food rocket fuel. Add all the granola, seeds, nuts, dried fruit, candied ginger, and M&Ms you want. Just be sure to store in a bear-proof canister because suspending from a branch in a nylon sack isn't going to do it.
