Maybe it's not the "baiting" per say, but all of the traffic in and out of the bait sites refilling the buckets, checking cameras, etc. That's what will turn the mature bucks even more nocturnal. A food plot is a little different. You plant, it rains and the plot grows. It continues to grow all season no matter how hard it gets pounded. Rarely is there a need to be walking around a plot during season, so it stands to reason a plot will have much less traffic than a bait site. My 2 cents.
