For all you hunters out there- do you ask farmers if you can hunt their land? I've been asked by a neigherbor, and I really don't care, but does the landowner have any liability?
I guess you technically could be held liable, but in Nebraska it wouldn't be likely. They like to encourage landowners to give permission. I reckon the exact statutes could be looked up fairly easily.
Never a bad idea to do what you got to do to cover yourself, though.
