I get the feeling E will enjoy the outdoorsy stuff, at least until he discovers girls, and even then if the love for it is there it will stick with him. What he doesn't know is that the memories he is creating now, with you, will stick with him for life.
Faith's dad died when she was 11 (he was 33) and she still recalls those times he taught her to ski (water), or fish or put the boat on the trailer and stuff like that...They are an 11 year olds memories but cherished just the same. One never knows when a memory may be the last we can ever create.
You should look into land navigation, you know, topographic map and compass. It's enjoyable and brings a person a lot of confidence when in the wilderness. It doesn't have to be complicated and can be a teach yourself thing. Whether you do or not though, what you are doing is good for E.
