The redoubtable Grandma-this books is a sequel to Grandma Drove the Garbage Truck-is at it again. In addition to collecting the town's garbage, Grandma and her sons also plow the roads in the winter. But what happens when a blizzard comes through, it's the day of the big town carol sing, and Grandma's sons are all stuck in the snow and unable to plow? Leave it to Grandma to clear the way to the church for the carol sing. With more help from her grandson Billy, she gets the streets clear and helps out her neighbors in the process, too. In fact, Grandma does such a good job with the plowing, she even beats Santa to the carol sing.
