My oldest boy who is 19 now used to love fishing with me, until school, work and girls came into the picture. lol I'm sure he'll turn around once his university is done. My youngest boy who is 14 totally loves going out with me whether it be on the ice, in a boat, on the shore or in the canoe. I'm sure he'll also go through "a stage" but I'm sure it'll just be a passing fad. I was the same way to an extent when I was in my late teens, early 20's....especially with being a dad at such a young age(20). Now I spend as much time fishing with my dad and my son as I possibly can.
Once a fisherman, always a fisherman.
Cheers,
Colin
