I haven't read the article yet, but I plan to. As far as creating competition wouldn't using the timed feeders do the same? That way you could have a 200 lb. hopper that puts out a small amount of food as a designated time. If the deer want to eat that food they better get there before its gone.

The problem I have in PA is that I use feeders for cameras more than I do for stands (it's legal in my zone to bait). The reason for this is are season doesn't start until October so by that time there are acorns on the ground and as Diesel alluded to the deer have changed their feeding patterns. They are still a great tool for getting pictures, but hunting over them with the intention of shooting a patterned buck is a difficult proposition at best.
