There could have been a request made to not display certain imagery north of a certain point, if you look at the image the darker brown area (almost a straight line east / west, the southern area) is a new image (11/17/2011), yet the lighter northern part is from 06/22/2011, so there may be more to see, you just cant see it for whatever reason.
Either way, the imagery isn't current, so who knows . . . . .
I still like the chicken farm idea!
