Up on the edge of the roof are two cows. One of them is lying down and gazing out over the busy street in front of the store. The other one is standing and looking down at the ground as if he's thinking about making a leap to freedom. Or better grazing.
Always the stickler for accuracy, SWMBO said they look like Holsteins except these are grey and white and true Holsteins are usually black and white.
Maybe that hot Arizona sun faded their color.
(Oh, and in case you couldn't tell, they're not real cows. They're . . . . cow-ikins.)
