I never have hunted a corn field before,just didnt know which they prefer.I didnt see any bear sign but will look some more.I may just set up on the muscadines for now and still/sneek hunt the corn field till I figure which they are using the most.Thanks for your help.

Muscadines while you got em for sho! They don't last as long as either corn or acorns, and the deer will be on them til they are gone. If acorns are falling especially white oak acorns, the deer will come to them as well as the corn, usually with a preference for the acorns, they've already been eating corn usually. If the food is really plentiful (acorns and corn) the acorns will have top priority unless there is just no cover where they are, and the deer choose the corn food source for cover. Regardless it sounds like you have found a great spot, just figure where they're bedding at and get in between and get ready for action. GoodLuck!
