My son is 39 now and due to business pressures of he and his wife owning a business and raising two girls the fire for the hunt has mostly burned out or burns very low. We play golf now and then which is plenty of fun for father and son to spend time together and I'm sure he appreciates it just as much as a hunt. The key point is spending time together as father and son whether it be fishing, golf, or hunting.
I have two grandaughter and 3 grandsons so there's hope for one of them becoming a hunter maybe.
