I was around 6 when my father started to take me with him when "hunting". I knew later that he wasn't expecting any real hunting, but just had me along to learn to sit and watch, but more so to learn about the woods and the animals.
(face it, how many 6 year olds can actually sit still long enough, or walk and hike far enough to "go hunting". I know my 9 year old nephew couldn't)
