Years ago I worked for a law firm which represented the Zamboni family, so I've always been extra-interested in the machines. Thus I was intrigued to learn about ZAMBONI: THE COOLEST MACHINES ON ICE by Eric Dregni. Looks like a fun slice of pop culture history. (Hat tip: SoCal Sports Observed.)
I learned via Amazon that there is also a children's alphabet book titled Z IS FOR ZAMBONI. Looks like a must-have for any young hockey fans, in particular.
For more info, visit the official Zamboni website, which contains the company's history.
