I agree that the loss of interest is there. No "glory" in a squirrel with no antlers is there. Let me find you boys an article a good friend of mine wrote a few months ago.
The gist is, alot of kids just do not get into deer/turkey hunting but will go bonkers for rabbit and quail hunting, where you can move around and talk.Trying to get a hyper kid to "sit, sshhh, and be cold" can burn an active kid out, whereas that kid will learn to wear you and a pair of pointers out once he gets his first covey rise.
This same guy also said "The tape measure is ruining hunting."
