I wish I had a picture/video to show, but one of my favorite tree-stand moments was in 2007. There was about 6" of snow on the ground, and it was silent. I looked to the east to see single adult bobcat. Then, I watched her and her three "kittens" stalk through the snow directly under my stand and into the cedar trees about 30 yards to the west.
It was opening morning and I didn't have a fur-bearer permit so I never considered shooting. Also, I think I could have taken them in hand-to-paw combat, but I'm glad I didn't get to find out.
