Well hunting food sources is best in the evening but you run into the problem of getting down and back to the truck without bumping deer. I'd hang one stand on a side of the field where you can see good but where u can get out undetected. Pretty much an observation stand. Hunt it to see exactly what the deer are doing. If you see a shooter watch what he does. Where did he enter the field at? Where did he exit? Try to watch what trees he walks in front of. The next time you get a good wind I'd go back in there really early in the evening and put a lock on up based on what the deer did from your observations. Try to stay as scent free as possible when doing this.... These deer should be starting to hit the food sources hard again any day now, so good luck Andrew.
