When I was a kid, someone told me cows will run the deer off. For some reason that has stuck with me, BUT. We were scouting just yesterday and my landowner has a few cows feeding in the picked cornfield I will be hunting near. It has been very dry ( least rain in history this August ), but had rained a few days ago. That made all the tracks very fresh. Man, the deer tracks were everywhere! The last few years, there has been so many deer using this field, maybe they gang up on the cows and chase them away. Jim
