I guess it depends on where you hunt. I hunt in the Adirondacks in NY several miles from roads (no ATVs allowed either).

I occasionally see an overweight hunter at night when i get back to the car - never out in the middle of the woods.

Two years ago I heard a shot and found an old man had shot a fat fork horn. Having done that long drag (which traverses 2 decent hills) I offered to drag his out. He took offense and said if he was too old to drag them out then he didn't belong in the woods.

I have seen him several times since and we always have a nice chat. I aspire to keep myself that fit.
