Sarah trudged through the muck, cold and disheartened.  The trees were getting thinner and thinner and the weather was getting worse by the minute.  As she was about ready to turn around and go home, she spotted something in the distance, something that shimmered in the flashes of lightning.  She ran toward it, scrapping her clothes and sending mud flying.  When she came to it, she saw it was a metal tunnel that was too dark to see all the way into.  She stood in the entrance, shivering, her head flicking back and forth from the rain to the darkness behind her.
