I' d hunt high in the AM and slip down around the edge of corn in the PM. Look for some staging areas inside the woods. Hard to give a lot more info without knowing more.

Additionally, I' d spend some time mid-day scouting that river bottom. If there is a lot of pressure in the area the big boys will often go deep into the nastiest area they can find.

Good luck... sounds like you got a great place to hunt this year.
