Have you ever butchered a Pennsylvania whitetail on the ground?
Out of over 100 deer that I've cut up in the past ten years I did two on the ground.
It's rarely the easier option for where I hunt.
And if I had to guess I would guess your answer would be similar. Although I have no way of knowing for sure.
Erno provided a fine response. Whether he's done it before or not.
