The ranger leaned over and whispered to me that she had given the men the machetes because they were both terrified of snakes and had refused to get into the swamp without some protection. After she gave them the machetes they had agreed to get in, but even heavily armed they were as jumpy as rabbits and stood holding their hands stiff and high above the water. Every time a bubble would rise to the surface of the lake or a tree would drop a leaf or a bird would peep, the giants and I would panic.
