Welcome to the board farming_cat fan, hell of a introduction.
What part of KS was that you were harvesting in? I'm guessing central KS (between Salina and Hays but closer to Salina) for the following reasons
1. Non Irrigated Corn
2. Water visible in one of the drone shots
3. Some Tree's but not ton's of tree's like in eastern KS.
4. The topography and way the field is laid out seems like its the edge of the smoky hills
