What's the minimum size land for hunting??
I'm going to say 2 blades of grass, a twig and a small stone is plenty large enough to start hunting on.
All jokes aside, the majority of the hunting I do is on about 3 acres. And out of that, there is about an acre that has always proven to be my honey hole.
Of course, that's on private property and the adjoining property is a rather large animal wildlife preserve, but I seem to get plenty of animals coming in and out of there through a shallow valley that goes through the back corner of our property.
Since April, there have been over 700 trail camera photo's taken in just the one spot. So, I don't think you have to own the Ponderosa to be able to hunt and enjoy yourself on it.
