I've had some interesting moments while hunting and backpacking.
When I was a teenager, my dad and I hunted along a river in Ohio. This river was often visited by people floating in canoes. It was early season in October and I was set up at a shallow riffle crossing in a pinch point between two fields. About 3pm I hear some laughing and talking coming down the river. It was a guy and his lady friend. about the time they get 30 yards upstream, they pull off onto a sandbar and she jumps out of the canoe. She was wearing a short one piece dress with a bikini on underneath. She hikes up that sundress, drops the bikini bottoms, and bends over with her backside and everything else facing right towards me. I never say a word. She does her business, jumps back into the canoe, and off they float, none the wiser that I just saw everything. And I mean everything. Best hunt of my life to date.
Another time, while backcountry hiking in Colorado, I set up camp near the old Haywood Fire area, right on top of a high ridge. I ate dinner, hung my bear bag, and got into my tent. I was with a friend and it was late, pitch black dark. I can hear my friend is asleep. All of a sudden I hear this loud drumming, almost as if it was a helicopter about to land on us. It was so loud and all around us. My friend remains asleep, even as I'm going "Hey man, do you hear this?" I was freaked out. Well, next morning we get up, and as we're cooking breakfast, I ask him again, "Didn't you hear that loud thumping last night?" He said no. We pack up and start on our way deeper into the backcountry and we aren't 30 yards down the trail when I take a misstep off the trail and break a twig and BOOM!!! A covey of grouse bust out of the underbrush and scare the life out of me. I looked at my friend and said, "Well, that explains last night."
