I agree with fishseeker.
Lets be honest here, most all of us have been tired after hiking all day, and just wanted to cruise the area for a bit...sort of stretch the legs the easy way. And, if trolling for a buck, you see one, we have all shot it. Not the romatic vision of you-being one with nature, stalking your game, and a quick clean kill, but you have done it, I have done it. Dumb luck.
If I kill a buck, seen while driving from camp to my intended hike, am I all that bad?
We have had some old timers at camp, who must road hunt. Our deer hunt area is brutal steep and treacherous. They drive, get out, glass, drive.... If they find a buck, they take the shot. This is part of hunting. Just like shooting at ducks from your boat as you set your decoys. I am sure not one of us would pass the shot on a 5x5 bull elk, who crosses the road at the end of a string of cows. I doubt there are many of us who would make the decision not to engage a bull they found while driving in their truck...
