In Montana I've heard a couple answers to the question, "Where do you shoot a moose?"
1) Between the ruts in the road. 2) On the uphill side of the road.
Eileen's first moose, her medium-sized bull, was about 125 yards from a Forest Service road--but downhill. Luckily it wasn't a super-steep downhill....
If you are really lucky there may be another option.
