No deer yet I did glass up some cows. And this is where I have a ? Do mountain lions roar. I thought no but I heard 1 do it 2 times then it grabbed a calf and the cows went crazy. Regrouped then they turn run back down towards the lion then he ran right by me. Not to close 47yards I got about of 10 seconds of clear view of him. Wild so pumped I hike here at night alone alot. One thing there tails are freaking long
