I often wonder how people on the trail would act if I carried a deer out whole like the second video.
You would need to go to Western OR to do that though. Deer down there average a lot less weight that the BT deer here in western WA.
I lived there for many years and even worked in a slaughterhouse for a while. For some reason, the BT deer here are quite a bit larger.
It's easier to put one on your shoulders down there. Not so much here.
