Not much public land in 2B... Some GL's in Wash. County portion, but your best bet is 2A, 2C. Vast expanses of state forest, and GL 51 in Chalk Hill is large... also Ohiopyle SP, Forbes, etc.... Mucho room to roam with little worry of seeing "Posted" along the way.
Look at the cooperative farms. And if you do hunt the areas, try and find the owners house and give it a knock and if he answers let him know you're hunting and introduce yourself. I don't know if you have to but you should and it's always a nice thing to do for them so they aren't worried bout strange people on their grounds. There's lots of does down there, and not many people take advantage of the cooperative lands.
