I've seen a couple lions here in Texas over the last few years, one up on the Red River and the other down here in the hill country. I shot at him but missed.
I was stalking into a ground blind stand when I looked over to my right and holy crap, there was a large lion, long tail and everything. Took me a minute to realize what I was looking at, then I also realized he was stalking something, looking straight ahead, and had not noticed me. That's very rare, they almost always know about you before you see them at all.
I would love to say I just misjudged the distance and shot right under his chest, but the truth is I had to drop my bow arm, cause I wanted to see if I had hit him. He jumped and ran off behind me.
A few minutes later I was sitting in my ground blind about 25 yards from this spot, and I had a sudden realization he might still be in the area and pissed off. So I got up into a tripod, and left the ground blind for another day.
