I get the feeling you're going about this the wrong way. Unless it's a lot of really fresh gobbler tracks, sitting over a few random tracks is a good way to not see anything. Same goes for trying to pick a specific spot on unfamiliar ground. Setting up in some random opening and hoping a bird comes to you is unlikely to pay off. You need to go in and listen for a bird, your plan needs to be fluid, and you have to work with whatever the bird gives you. Be ready to adapt on the fly. I would also be looking to get a lot farther off a main road on public land. The general area around that first photo looks like it has potential, get out there and follow those creeks and streams and I think you'll find one sooner or later.
