Arkansas Puppy Mill?

It's a little hard to make out in this photo, but this entire hillside was covered in dog houses and dog pens. I could hear the non-stop barking a half-mile away, then when I came into sight, they really let loose with a cacophony of sound -- hundreds of dogs making as much noise as they could muster. Needless to say, I didn't stay long. Thank goodness (for me at least) they weren't all running free!
