Your state website probably has maps that you can download. Use those, combined with Google Earth to get an idea of what you're looking at.
Then boots on the ground until you find some spots that you like.
Allot of people complain about or even refuse to hunt public land.. And it certainly has its challenges.
But I look at it as an opportunity. I don't have the money to own or lease tens of thousands of acres. But by accessing public land it gives me room to stretch my legs.
Personally I'd rather hunt and explore all season on large chunks of public land and get nothing. Than to have a guaranteed spot on 5 acres of private where I was stuck in one stand or blind.
Thankfully I have a little mixture of both available to me.
