When I was a kid I used a mountain bike to follow an old railroad bed up to a good area, I used a plastic sled to pull a nice blacktail back out. It was pretty flat, but not too bad a pull at all.
Oh nice...look at the mods to those bikes. Something on the bars and something that comes up behind the seat. That could work for a whitetail...what do all you elk hunters think?The NVA used lots of bike to carry heavy loads down the Ho Chi Minh trail.
Sling it and push it.
