I am not a lawyer, so can't speak to the legal issues of road hunting in Kansas, but here is how it was explained to me. In Kansas the landowner owns to the section line, which will be the center of the road, should there be a road. If there is a road the township has an easement on the private property for the road. That road easement will be half on one side the section line and half on the other. In Kansas the road easement is for only road use by vehicles and utility company use and does not give the township or public the right to hunt in those road easements.
There are places where there are no roads along the sections lines and according to what I have been told, the public has no legal access to travel those section lines.
Maybe there is a Kansas attorney on here that can give better and more accurate information, but that is the way I understand it.
BTW, I believe in the regs a few years ago, it stated that to hunt the ditch you had to have permission from the landowners on both sides. Also, I think at one time the regs said on railroad right of ways you had to have permission of the railroad, plus the adjacent landowner.
