You feel adventurous today and you and your friend decide to ride your bikes to the edge of town and check out the woods.  You find yourself on the edge of the treeline and you both look at each other.

“Well, what do you want to do?” asks your friend.

As far as you can see, there’s a creek that starts just after the treeline.  You know if you follow that creek you won’t get lost (39).  There’s a set of animal tracks that lead into the forest going the opposite way (40).  Or you can just head forward into the woods and see if you see the glimmer (41).
