Good job Dan! That reminds me of my younger days when there were hogs on every farm in the neighborhood, and many structures that resembled yours. I like your blend of available materials - chain link, panels, used tin, and that Ford bed that will stay for the duration. The only thing that looks out of place is the blue gate. And don't think I'm trying to be a smart alec - I've had hogs in the same conditions, and they sold for the same price as the ones raised in the mortgaged facilities.
For the critics, just remember: those that care don't matter, and those that matter don't care.
