I encountered the same thing in the 520 unit last week, my first time hunting in washington, I got in past the crowds and thought I was alone for three days, got close to two cows that were already acting jumpy and they scattered when I was about 50 yards out, I went to track them and found poop smeared TP on the ground bone dry which means it was fresh. I tracked the cows a few hundred yards and found a pile of poop from the days before, (TP had been rained on) ON THE GAME TRAIL! later I found a power bar wrapper that wasn't there the day before. Then I found a piece of the same TP on the road leading in that evening. Not an activist, just an ignorant hunter that doesn't know how to hunt i.e. too lazy to bury their poop and to do it off the game trail. Well that explains the weird call I heard the day before followed by four cows being spooked uphill from me,running past me and down into the swamp. I thought they'd smelled or heard me but now I know better. I hung it up and went home after that, I figured anyone stupid enough to wipe their butt on the game trail they are hunting is probably stupid enough to take a sound shot at me.
