Staying hydrated is important when you are out on the trail, but eggs, mayonnaise, bacon, and a head of lettuce are a little overkill unless you're pulling a trailer or have a pickup bed to fill. Consider a small, collapsible cooler for drinks that you freeze ahead of time, so no additional ice is needed. As for food, we find an eight-piece bucket of KFC chicken good for a weekend. Big boys may wanna double that. Cold pizza works well too, and it stacks flat. No, we are not even kidding.
