Definitely apples. We can't hunt over bait in PA, but I like to run a trail cam near my home in the suburbs where I don't hunt. I go around the neighborhood and pick up apples on the ground near peoples apple trees. I also asked the neighbor if I can have the ones that fall in his yard. He says yeah because he doesn't have to pick them up - I do it. I usually slice the apples in half or quarters. It releases scent and they spend longer eating them.
