Grew up farming and ranching in Nebraska, I speak farmer real well. My Dad long since retired but still drives grain trucks in the fall. All the ground in NE that we used to shoot on has center pivots and corn on it. That gets rid of the dogs pretty fast.
I usually buy the county plot maps for where I'm looking. They'll list the owner and a phone number. These days most are trusts or corps so it's kind of hard to figure out who owns it.
I'll just have to invest a weekend and a bunch of gas. It's kind of like going home talking to all the farmers so its enjoyable (just expensive these days).
I appreciate the feedback.
