I can' t answer to Lawrence county but I can tell you that not all state game lands have been loaded onto their website yet. I think the website is new as of this summer and they are still working on getting some information on there.
I can tell you to avoid the state game lands in the northern section of allegheny county though.
Here is another forum that is mostly PA hunters. Maybe you can get some help there. Most guys won' t post their hunting spots online but they may send you a PM or email.
