If you want to own and control your 40 acres, you'd be advised to fence and cattle grate up.

Apparently, if you are not a rancher, you're a farmer and need to learn about barbed wire.

Open range laws vary from state-to-state. Apparently on the “open range” if you don’t want someone else’s livestock on your property, you have to fence them out.

Hit a cow, you must reimburse the rancher. Who *owns* this land, anyway? Things are murky, to be sure.
