You continue up the hill. Soon you come to the top. You look out over the valley end see something in the distance. It appears to be a small town of some sort. You can see smoke wafting above it. You realise that you have taken the wrong path. You look back the way you have just come. You notice that about a hundred feet behind you, the track goes two ways. You never noticed it on the way up. You have to make a choice. Do you carry on, or head back down the hill to the town?
