As a 17yr old I carried the hindquarters of a highly worked up and fat stag for 4 hrs and arrived at the hut to discover the meat was "green". Silly green me had not let it air or cool in any way on way out and had wrapped all the skin around and between the legs so not to get blood on my back.
It was also a stinking hot day.
First, second and third rule is cool animal/meat before an extended carry.
