Don't want to discourage you but it's not going to be easy. It can be done though. I found as much bear sign in the last few days as I've seen all season. They were feeding on mt oaks and grass patches. Just get out and look. Anytime you can get in the woods and learn new places you will have more knowledge for the future.
Last year I didn’t see any bear sign in December, there weren’t really any acorns though. The year before there was decently fresh sign, but not much and I bumped into another hunter that saw a bear busting off a ridgeline. I don’t think Chestatee is really known for bears like some of the other WMAs, but you never know what may happen.
