I live about 20 minutes from Mohican forest, on the edge of Knox and Morrow county.
The beans are pretty much all off around here, and they are starting on the corn. I would imagine by the end of October that the corn will be off and you'll be good to go.
Good luck! Mohican is a little known treasure. There are a lot of little areas that aren't hunted...and the number of monsters roaming that area is astounding.
