I am not that familiar with the public land you speak of. You should go to the ODNR web-site and look into public land opportunities. Around Columbus there is the Delaware preserve which tends to yield some really nice bucks. There is also some unique opportunities like in southern ohio where there is Mead property that ODNR has purchased.

I recently purchased land in southeast ohio and am falling in love with it. Wayne National Forest has always been considered a good place to hunt for big bucks.

In general southern and eastern ohio offer you the best opportunity for large bucks... But that is just in general... Big bucks reside throughout Ohio.
