There is always at least one Luna bar in my pack. They're delicious, and good nutrition in a junk food world. I have a special weakness for Iced Oatmeal Raisin. I find Luna bars to be a good size for those times when you really could use a meal, but for whatever reason, can't get to "real" food. I will admit to eating nothing but Lunas for an entire weekend on at least one occasion (That's probably not recommended, however).
