Although I do not restrict my view to the pavement, I do look down a fair amount (and I still manage to trip on a curb now and then!).
I believe this is the north east corner of the intersection of Michigan Ave. and Ontario in Chicago (towards the north end of the Magnificent Mile). I believe the figure is about ten inches in length.
This is a shot of a sidewalk grate in Chicago. I am fairly certain that I am not the first person to be taking a picture of a sidewalk grate. I was struck by the contrast between the order of the grate and the disorder of the debris and the texture of the debris.
This is on the roadway of Airport Expressway Road in Fort Wayne.
