I've told people how to catch fish in certain areas, but they still won't listen.
Now when it comes to deer hunting, the level of risk increases, imo.
Some people are just hateful and think they will live forever.
When I was much younger, I had older men tell me about different ways they would catch fish. Some worked and some didn't.
Now giving away my favorite fishing spots for any particular area, my family knows about them, and I have told one very close friend, but I do admit I would be reluctant to tell a total stranger where my honey holes are.
I knew a man who had some really great morel mushroom spots, and he took them to his grave.
I don't believe I want to live my life that way. I'm not going to give away any information that will create a mass exodus that would wipe out any species of fish or deer.
Everything depends on the circumstances and individual.
