Every buck is different and unique. If I harvested the biggest buck in the state when I was 25 I would certainly still be hunting. If you broke the state record for a certain fish species, would you quit fishing?
The question doesn't make much sense. I'm pretty sure Milo Hansen still hunts. He probably hunts doe, too.
It's just fun to know there's a big buck on your property. Makes time in the stand more exciting. It also helps to pass the time in July.
