The ban is already in affect where I'm at and has been for a good while, I can sell farm to farm but I can't take them to swaps and that's the best way to sell them is to take them to swaps in my opinion.
I'm not sure exactly all of the states that are affected by the ban but I know Kentucky is affected so no, North Carolina isn't the only one with the ban. All I know is I hope they lift it pretty soon!!! I have a lot of biddies I need to sell!!
