It's not illegal to hunt from the road, it's illegal to shoot from any vehicle and/or within a certain distance from the road. State laws will disclose that distance.
QDM is foodplots and mineral licks for the deer, but some states have made mineral licks illegal.Bottomline is read/know your state's regulations and carry the phone number to your DNR-Law Enforcement, in your Cellphone and use it. Get the "Slob-Hunters" off the roads and out of the woods....
Works for me!
