Oh so long ago when I drew this one, I kept hearing "Sidewalks aren't like that! You drew it wrong!" I'll point out now a few things :
1. This picture was drawn when I lived in Pittsburgh
2. Pittsburgh sidewalks really are that bad

Also noted by many, was the No Loitering notice on the Bus Stop sign, which seems to contradict itself. You wait for the bus here, but you're not allowed to wait around here. Yes, that sign also exists in Pittsburgh, and yes it's in front of a shop that has a blank wall right in front of the doorway.

As for the squirrel, you'd be grumpy too if only half of you was evil.
