When you take something for granted, you often lose it.
History and personal experience have shown this to be true of much, if not all, that is important. It is true not only of our possessions, but also of our relationships; health; traditions (including hunting, fishing and other outdoor traditions); clean soil, water, and air; wilderness (and more broadly the beauty and availability of those spaces where we engage in our most cherished outdoor activities); freedom (of all types); and the very food that will tastefully (and abundantly) adorn our tables this Thursday.
