Shortly after reading "Mike Mulligan and His Steam Shovel", my family traveled to New York City, where my brother explained that the steam pipes rising up from the pavement were from the steam shovels that had dug the skyscrapers, and had subsequently been paved over. I felt so sorry for all those poor, trapped steam shovels! He reassured me that they got out when there was road construction...
