Seems to be happening quite a bit these days. Either the older guys are passin on and the kids are selling out or more and more folks are getting into the leasing their property out. It's everywhere here, but then again, I live in Howard Co. Maryland, dead smack between B'more and DC. High rent district in this neck of the woods. I have been hunting public land the last couple years (mainly in Garrett Co, not too far from Deep Creek Lake, DCL). I was hunting on a friends private land but he got in $$$ trouble and sold it off. I know where your coming from, firsthand. DCL is a good 2.5-3 hour ride from my house and unimproved forest land sells in the $6K/acre out there and the closer to home, the price shoots up, real quick. Most private land of any size anywhere in between is already leased out.
How about joining a hunting club in your area? It can be cost efficent and open some good hunting to ya. I hope to make a move on some land in a couple years. Maybe a cabin on a couple acres that backs to a national forest? That's the idea, as of right now.
Good luck on your search and don't be afraid to knock on doors and ask about hunting. Maybe you can find a nice spot you and a couple buddies can pool together and lease out.
