I took a "mentored youth" (a debatably cool PA thing where an underage kid can go out before getting a license, where the mentor carries the gun at all times till they are in a solid position ready to shoot) who was like 8 years old turkey hunting. It was the kid's first hunt and he was so excited he couldn't sleep. We had practiced with the shotgun a couple times and this kid was ready to roll, full of enthusiasm and light on knowledge.
We got set down extra early next to a huge oak along a food plot field and set up a feeding hen decoy about 15 yards out. Birds were going wild all around us right before shooting light then definitely quieted down once it got light. Then one got fired up about 100 yards away down over the hill to our right. Those gobbles were so loud they were shaking the ferns. I would barely get done with a little clucking sequence and that bird would fire off again. To put it mildly, he was heading our way. About that time, I heard a twig snap behind us and thought for sure it was a bird that had come in silent. I eased around the tree and there was a bear cub about 10 yards away, with his brother and momma another 10 yards behind him. They were all fixated on the decoy and never saw me. I immediately explained the situation to him, grabbed the single shot 20 gauge, started jamming shells between my fingers asked the kid which way he thought the house was. After he pointed 180 degrees in the wrong direction, I told him where the house was and told him if anything happened to me to beat feet that way and that one of my relatives on the hill would probably get him back to my grandparents' house safely. I removed my camo mask and stood up. The nearest cub was at about 5 yards now and his ~6' tall momma was now standing up woofing at me. I'll never forget how big that kid's eyes were when he popped around that tree and finally saw that bear. I started doing the old Alaskan "hey bear" quiet yell and she got down on all fours and lowly grunted and those little cubs just turned on a dime and followed after her. I told the kid we weren't going call for a little and though a bit disappointed, he was totally ok with it. Needless to say, the bird never showed.
The best part was when we returned to this kid's house to report on our hunt. When his super-protective Mom asked how it went, the first words he said were "WE GOT ATTACKED BY A BEAR." I told him if he kept telling those crazy (albeit almost true) things to his Mom we would never get to hunt together again. It's been almost 15 years and we've hunted together almost every year since and have never gotten "attacked by a bear" ever again.
