/*
  Running for Water

  Colors follow Team World Vision: their orange for race bibs and primary
  actions, a water blue, and the yellow of the jerrycans people carry water
  in. Big Shoulders (a condensed face drawn for Chicago, home of Team World
  Vision's biggest marathon) sets headlines; Lato, Team World Vision's text
  face, sets everything else.
