I've been through this with my oldest son whose now 17.
He's a crack shot and liked to shoot 3D when he was 12-16 and won alot of 3D shoots, but didn't really want to hunt when he got old enough to. (Girl Friends)
I REALLY wanted him to bowhunt with me, but it seemed like the more i talked about it or tried to get him to, the less interested in it he became, so i no longer push him.
He's a really good shot and he doesn't practice as much as i want him too, but thats fine as long as he understands what he's up against in the woods.
He went one afternoon last season and took his compound with him and thats fine with me because he shoots it well, just not as much as he shoots his widow.
He came back to the house and seemed a little perplexed almost like he was avoiding me on purpose. I knew something was up, so i waited untill he was ready to tell me what happened.
He dropped his bow out of the treestand.
I also believe, There's to much of the trying to keep up with the world going on with teen's nowadays. Techno junk, facebook garbage and so on.
