Something I think is interesting, and I will admit I have not read through this whole thread, is the difference between a feeder and a pile. I've been experimenting on this with the yard deer behind the house this fall. I've got a hanging feeder with a motor. I had it set to feed roughly an hour before dark and an hour after sunrise. So in other words, the corn is on the ground in daylight. I'd still not very often see deer at the feeder during daylight. And I've got a camera there, so I'm not relying on visual sightings. If I take a bag of corn out there and dump it, within a day or so, I start seeing a lot more consistent daylight deer. It's like there's a bigger draw to them, knowing it's on the ground and they can see that it's there. Maybe I'm giving them more credit than they deserve, but I 100% see a difference between loose corn on the ground and a feeder mechanism delivering it early morning/late afternoon.
