You are talking maybe 5 bear hunters looking for 5 bears. The bulk of the grizzly population would never know they were being hunted. The few that get seen will get shot, all the while the bulk of the population had no idea anyone is looking for them.
You ever take a piss in the woods? You think you might leave some scent?
Oh never mind. No one here ever has a light bulb moment and suddenly gets it.
