I understand the motivation and desire to supplement and bait. I don't have any dogs in the fight. Ohio says it's legal so it's legal. I don't even have an issue with them!
Here is the heads up. Penna. Game Commission believes that the spread of CWD (now in Ohio in wild herd) is happening from places like bait piles and mineral supplement gathering places. So enjoy them while you can! You may want to consider though ahead of time just what we are facing over here in Pa.
Now I'm pretty sure it got here through "deer farms" which were not allowed to be managed by the Game Commission thanks to Harrisburg politics. Could be the same down your way too. Stay ahead of it folks and stay on your ODNR as well, not to keep the baiting and mineral rocks necessarily, but to stay ahead of the problem. There is no easy answer here...
The Game Commission might expand disease management boundaries for deer as 212 tested positive for Chronic Wasting Disease over the last hunting season
