Bartolomeo Mecánico has taken the trouble to make an archive of road signs that compare interpretations of Men At Work, Children Crossing and Falling Rocks throughout the world. [Link]
Be sure to visit the Boulder Count page which shows a statistical distribution of the numbers of boulders that appear on Falling Rocks signs in different countries.
Bartolomeo, you are hereby inducted into the Tetherd Cow Ahead Society of Treasured Humans as the inaugural member.
Three cheers for Bartolomeo!
