At the starting point of the "Frosty the Snowman" book walk, Nolan Davis, 4, and his brother, Lucas, 1, posed for a photo with Nolan holding a copy of the book they just received from Bookie's New and Used Book Store around the corner. The boys did the book walk Saturday in downtown Homewood with their mother, Kristina Davis, and their aunt, Elizabeth Menig, following the adventures of Frosty in big window displays on the east and north sides of the Triumph Building.
