It's amazing what the old-timers knew and as a kid I foolishly dismissed them as wives tales. I went in to a stand a few years ago about 2pm, it was early October and the days were still long and hot. The cows were all moving in every pasture I passed. Long story short, I blew eight deer out of the creek bottom and two looked like good bucks. They were all up feeding. That night a big storm blew in and I believe they knew it was coming. I got a big fat "I told you so" on that one. So if the cows are milling around I pay particular attention.
