John Marsh is backpacking through the swamp, wearing very short jean shorts and knee-high moccasin boots. The terrain he is traversing is fraught with unpredictable ground that likes to swallow his boots and make him struggle to pull his feet out of the sucking mud. The deepest mud he finds is just over his knees. There are lots of great sucking sounds and brief struggles as John tries to get back onto solid ground.
