My home state of Minnesota has a mid-September archery opener. This means that during the first weeks of season, I'm hunting bucks that are still on a summer bed-to-feed pattern, often within a fairly small core area, and still hitting the immediate area's top food sources. If my summer cameras (which I typically place on mineral licks near a food source) consistently reveal a buck in an area, I make a point to take a close look at the top food sources nearby. I'll look for the obvious alfalfa and bean fields, of course, but I'll also note if an alfalfa field was newly seeded in the spring, for example, which makes it especially attractive. I'll check the oak and apple trees, too, to see which are apt to yield the most mast. Unforeseen nuances will come into play--a farmer may cut a corn field earlier than usual, let's say--but my knowledge of the food sources will allow me to make quick adjustments and stay in the game.
