I believe 2x2 is roughly 300 acres & then another 160 acres, so roughly 460 acres.
I'd put a stand at every major draw that runs into or out of a crop field. Ive always put my stands 50 to 100 yards into the draw off a food source. That way I can catch em coming or going & alot of the time they use those spots for staging or bedding. I always hunt the draws & ridges but it looks like the ridges there have no wooded cover, so I'd hunt the draws. But I'd then find which draws they're traveling most & be ready to change sets just as soon as they decided to change travel corridors. If it's not wooded, I don't hunt it & I don't really care for hunting field edges. I stick to the thickets in the draws & ridges.
Your grounds there actually look alot like the one we hunt except our ridges & hilltops are covered in hardwoods.
