This clip was shot entirely on the GoPro in bright sun, so the quality varies depending on which way the camera is pointing. This is an exploration clip. John slogs through all sorts of mud. He's not actually trying to sink, but rather to navigate the terrain so he can discover what is over the next hill ... metaphorically speaking ... there are no hills in the swamp. He encounters very deep mud that he can't cross with his equipment. By the time he's finished, he's pretty torn up from the swamp grass and he's ready for a break. It's an adventure and it's all real.
