This is part of the Mead paper mill in Chillicothe, Ohio. I snapped this from the car window as we were driving along (you’ll see the door frame in the top left). Since going back to college I’ve always tried to buy Mead 5-star papers/binders when getting school supplies. It’s nice to be reminded from time to time that things are still made in my country, and to have a part of that so close to where I grew up.
edit: It might not be Mead anymore, but it’s still around. I found this article.
