I found an error on the map, in the area I always hunt. I know the landowner, just called him, and he said he would run-off anyone that tried to hunt that parcel. He will call the game warden, and I just called CPW to get them to, hopefully, correct it.
In case you are going to the south half of Yuma County this season, the parcel shown at Vernon, which indicates the west half of the section that includes Vernon (Sec. 28, 1S 44W), that half-section, indicated to be wheat stubble (W), is not walk-in. I think it is likely corn stubble again, as that field has been corn for over 10 years. There will also be cattle on it, if it is corn stubble. Don't hunt that half-section.
Just an FYI that the atlas is not infallible.
