I still hunt both public and private lands. Always have, even 50 years ago as a kid.
My home is in Chelan County, Washington. About 85% public land. Pretty decent hunting, nothing extraordinary, however the county is home to mule deer, elk, black bear, as well as quite a bit of small game & upland bird hunting too. Nearby counties have some very large farms, some of which I've been able to hunt.
About every other year I treat myself to a combo hunt for mule deer & pronghorn antelope in Wyoming. There's 40,000 acres to hunt, and I've never seen more than three hunters at any given time. We have breakfast together, we might hunt together or maybe separately, and then we have dinner together in the old ranch house. Yes, I have to pay for that place, but it's a real nice hunt.
The rancher counts on hunters for part of his income, and is diligent in maintaining some habitat for the animals. It's a good place.
From my experience, there's still a lot of public land hunting available, and some private land can provide excellent hunting opportunities as well.
I volunteer with the Rocky Mtn Elk Foundation, and we've done some decent work on public/private partnerships, helping the deer & elk habitat, helping hunter access. Consider putting in a little volunteer time, or supporting outfits like RMEF or others, with a bit of cash. It all helps.
