i have permission to hunt several farms and ranches. Sometimes help out on two of those places.
Never, ever take another hunter onto property you have permission to hunt without first getting the landowners permission. I know two guys who got kicked off farms for taking their buds along. A friend was kicked out of his lease when he invited another hunter along. That hunter came back with his buds, they got caught by other hunters in the lease and it was all over.
There is nothing better than owning hunting land; too bad mine is 75-140 miles from home, except for our place in WV which is 1,250 miles from home.
