When my husband and I came across a situation like that, we spoke to the unit game manager to get landowner names and ranch names, then I went home and got on the internet too look them up. It really helps out if you can go do some scouting and when you talk to the landowners and let them know that you have looked around, it seemed to make an impression on the landowners that we were out looking and not just trying to get access to their property.
