Jason,
I come from a hunting family with lots of mentors, both family and old guys from my dads hunting & fishing club.....I have 2 sisters with 5 boys and none of them hunt (& I've tried to get them involved)…..I had 3 uncles and all of them hunted and their sons (4 cousins) all hunt, but none of their sons really hunt.....My female cousins (6) didn't marry hunters except one and their son does hunt.....So 3 generations and only one of the 3rd generation hunts.....This is how you lose hunting.
I've also got friends where they have sons and only one (or none) will take up hunting even though their dads are hardcore....I can only think of 2 daughters that hunt....I guess the point is, all we can do is try to introduce them to it and hope they enjoy it as much as we do.
Yes, we have lost a lot of local hunting.....I was raised in Long Beach, but lots of hunting opps near by in Orange, Riverside, and San Berdo Counties.....We have also lost hunting opportunities in our game itself.....SoCal was loaded with quail, ducks, geese, pheasant, and dove.....Now we have little opportunities for these species within an 2 hour drive.....We also had a DFG that enhanced hunting.....Planting of pheasants was everywhere in the state....And it was FREE.... Duck hunting?....7 ducks and you were good to go.....Deer hunting was simple.....Buy a deer tag and hunt them wherever you wanted.....Chukar & turkeys were introduced to help hunters numbers.....There were bounties on crows and mountain lions.....Why?....Because it helped our game animals.
Despite all these negatives, we still have lots of hunting opportunities, if you seek them.....Ask lots of questions on social media (like SCH), watch videos on YouTube, ask friends to go shooting at a club (most have public shooting days), join a conservation group (like NWTF), and accept you're going to have to drive some.
