I'm one of those 8 hunters and can verify what Yommoma says. One season we tagged out on opening morning.
Well, if your goal is simply to tag out, then go for it. I don't doubt that several people on 100 acres would likely see some deer. However, I like to hunt.
I have never tagged out on opening morning. I have passed on many, many deer on opening morning because it would have meant my hunting was over for the season. Unless it was the biggest buck I have ever seen, I likely wouldn't ever shoot on opening morning. My goal is to shoot a decent buck or big doe in the last hours of the last day of the season, and my wife will tell you she laughs at how often I let too many go by during the season and end up with nothing. Until then, I hunt as many days as I can in areas where I will encounter the fewest hunters possible. My partners (a couple of close friends, and maybe our kids) and I often go whole days hunting and encounter fewer than 8 people.
My point is that our goals are not just to kill an animal, but to hunt in satisfying, enjoyable ways. We often stop at noon, start a fire, and cook sausage while we talk about the day or maybe our lives, or even the state of the planet and make plans for where to go in the afternoon. We really like to eat deer, elk, moose, antelope, ducks, geese, upland game, rabbits, make our own sausage, jerky, etc., but hunting is the primary goal. We still hunt almost exclusively. The goal is to shoot a huge buck in its bed. The crown land community pasture that starts about 10 km south of my house is over 100 square miles. A mid week hunt will have us encounter maybe half a dozen hunters in a day, and we usually try to talk to them so we can avoid each other the rest of the day. Occasionally we will see another truck from a half mile away, and just go somewhere else. If we really want adventure, we will sometimes drive to areas we know that are much larger areas of forest land and hunt there, sometimes camping as well. Somewhat less of that as we age, I guess.
So, although I understand that deer can be killed in many ways, our style of hunting needs MUCH more than 100 acres, and I love our style of hunting. At my age, if I was told I had only 100 acres to hunt on from now until I died, I'd just stop hunting. I know that access to hunting land is diminishing rapidly everywhere, and just this last season one of the conversations around the noon fire was about how much access we have lost since I started hunting with my father and uncles 60 years ago, and how what we have would not likely last until our sons were as old as we are. I hope you can all understand how astonished and saddened I feel that we have a thread here talking about hunting on such small parcels of land.
I'm not trying to disparage anyone who does. I'm sad that anyone has to.
