Rules to play Hiking
Play it smart
Taking on a threeday hike when you havent exercised in years its certainly not the best choice. The same is true of going on a solo hike if you dont have the experience and preparation for it. Even when going on a hike with somebody else, always let people know your destination and when to expect you back. If something happens and you dont turn up, a search party will know where to look for you.
