I just checked my trail camera's today, and I have a ton of elk pictures every day until the cows moved in. I went from getting probably average of 50 elk pictures a day to less than five a day once the cows moved in. It is amazing how much the elk change their patterns due to cattle. Also on the day I started to get pictures of cattle, I don't have a single picture of elk in daylight. All the elk pictures from that day on have only been night pictures. Just one of those things.
