You consider the cave, finding it much too ominous, then the field, and see there's clearly nothing there but plants, and decide on the forest. There's no clear path, but the trees aren't as dense as the had seemed from without. You're walking absently, lost in thought, when you almost stumble into a deep ravine. It seem's there's no way around, but if you're in the mood to channel your inner Tarzan, you could swing over on one of the many vines, but that's not your only option.
