At the time, climbing up the tree seemed like a good idea. Andy figured that the jeep couldn't follow a group of tree-climbers and if one swung from branch to branch it would make someone a hard target to hit. But then Andy was not strategist and when the guy who had refused his hand talked about the gully that sounded like a much better plan. At least one other person was co-operating surely that was a good sign. Andy swung down from the tree and started running (or rather limping, his leg was getting quite painful) in the same direction as the man.
