A friend of mine was bow hunting in Idaho some years back moving slow. He said he didn’t actually hear anything just had an eerie feeling and looked behind him to see a cougar some 8 or 10 yards away stalking him.
Fortunately he had a sidearm and fired a round that that spooked the cat.
That is what gets you, you never see them till its to late. You need to walk tall and keep your kids close in M lion country. I never let my grand kids run “up ahead” when we are out walking. The cats are just doing what they do it’s up to us to make sure they do not have the opportunity.
