I was working a bait just outside of greer 4 years ago when a sow and 2 cubs came in, the sow became very interested in my pop up blind. She came up to it and sniffed it and pushed on it. Then when I thought she was leaving she turned grunted and stuck her head right in the little shooting hole, and began sniffing. All I could think about was "i'm a dead guy." So I did what seemed like the thing to do, I popped her in the nose with the braodhead that I had sitting on the rest. She backed out and let out a screaming cry that I will never forget, and the cubs went screaming up the tree. Momma came back about 15min later calling for the babies just like in that video with a bloody nose. She never looked back at the blind. Once the cubs came done she turned and led them out, and I departed quickly the other direction to get the crap paper and a new set of drawers.
Always practice C&R on native steelhead.
