To those who love mushrooms, what could be finer than sauteing up a mess of freshly collected 'shrooms to go along with your freeze-dried dinner or the trout you hooked in the backcountry of a national park? A teaspoon of garlic, a dash of salt, and a couple cranks of the pepper mill and you'll have a wonderful complement to your meal. Unless, of course, you picked the wrong mushroom, in which case this could be your last meal.
