I can definitely relate.  I grew up hunting, and since my folks ran a hunting preserve I was guiding once I was old enough.  Now we live in a city and find that accessing hunting land is not easy.  Hunting clubs have leases on most of the better hunting land within a reasonable driving distance.

I took my kids camping and we took along firearms to plink with when they were young.  My kids were 9-years apart in age and I took each of them hunting when they'd reached an age where I thought they would do OK.  I didn't have much luck with my daughter.  She'd go through the motions but it wasn't hard to see that her heart wasn't in it.

Things went better with my son.  He'd become interested in dogs and we hunted birds over "his" dog a few times.  That came to a sudden stop when I did something I'd done hundreds of times as a guide.  The dog retrieved a quail that my son had shot and it was still alive.  I immediately broke its neck to keep it from suffering unduly.  Something about that didn't sit well with my son.  In the end he seemed to understand why I'd broken the quail's neck, but he never again hunted. 

Both of my kids have now gone Vegan, not because of animal rights, but because they believe it is a healthier lifestyle.  I'm zero for two with passing on my hunting heritage.
