Took my oldest boy last year, he's 8 now but was 7 at the time. I bought a ground blind so we could do this. Darned thng was too small but thats another story.
Anyhow, he promised he'd be quiet & I had a good spot in mind for the blind so we went.
I tried setting up so the deer would go by my window first & I might get a shot after they walked past. Well, didn't work out that way. He was quiet I'll give him that & it was cool watchin the squirrels & chipmonks rootin around. Then a deer came, nice doe, from his side. I watched her come in & couldnt tell him because she was too close, he didnt see her cuz he was lookin where I told him to look & when he turned that way he saw her & let out a "There goes one dad!" that woulda woke the dead. He felt kinda bad after she ran off, but think he looks at it as a sort of lesson.
I got a bigger blind this year & he'll be back out with me.
