Gil,
Most of the areas I have hunted here in Ohio have had a number of coyotes. I don't think you will get away from them. Every county in Ohio has them now, you will even see them in bigger cities like Columbus. That being said, I don't think they affect the deer as badly as some people think (IMO). Ohio is loaded with deer. I used to drive I70 between Columbus and Zanesville everyday. During the rut there were 3-4 new dead deer every day on my drive. I also saw plenty of them out in the fields, even later into the morning. They are here if you are willing to do the work, which I'm sure you are. I can't imagine you would make that drive and not put in the time. You will see deer at Dillon, just get a good plan and be patient. Like someone else said, squirrel hunters may help you out.
Try to find where most of the less motivated people will enter the public hunting area and slip in the back tougher way. That is why I thought you might want to see if there is any access from the water at Dillon. I have never tried it myself.
Again, you will see deer, good luck!
