It’s 5:15 pm. You’ve walked twenty-eight kilometres, and you feel every bit of it. There’s a dull, weary pain emanating upwards from the soles of your feet, and, alas, you’ve already eaten your chocolate for the day.
Even though you’d like nothing more than to lie down on the nearest patch of ground – and all ground is comfortable at this point – you’re at an intersection and you have a decision to make. To your right is a five kilometre ascent to a mountain shelter of unknown quality. From there you could summit the mountain of Crnopac tomorrow, before heading back down to the town of Gračac. This is the plan, but there’s thunderstorms forecast (it’s already raining) and Crnopac is too dangerous to climb in bad weather. So instead you could turn left for a five kilometre descent straight into Gračac and the bed that’s waiting for you there.
What do you do?
