The snow exposed to cars is covered in grimy residue, while the snow away from traffic remains clean.

    As a kid in the city, the bottom picture was pretty normal to me.

    I now love a bit farther away from high traffic areas and it sort of looks like the above. I still see the nasty residue.

      I moved in the country, and if I say jog on a back road here, a single vehicle might go by, and fouls the air for a couple of minutes. In the city I wouldn’t have even noticed it, there would be a thousand times that in the air at any given moment.
