One, I do not drink or throw out beer cans while hunting. Wilderness is clearly defined and protected. Private land is private and what one does on his land, as long is legal is fine. Lumping all hunters as beer can throwing....is the same as calling all homebrewers alcoloholics. Wrong. What you have might be nice, but clearly not wilderness hence what they do is legal.
Also, I drug my deer a half mile, vehicles weren't allowed off the road.
