John,personally if it was me I would use the food plots as an evening spot.To get there early in the morn and not spooking any deer in the plot would be next to impossible.Be there mid afternoon till dark and thats when its going to happen.I would use your stand in the bush by the corn field in the morn,especially if you can sneak in real early and get the deer as they slowly sneak out of the corn and into there bedding areas.
