The Los Alamos Daily Post shared this picture of toddlers dancing at the Mesa Public Library in Los Alamos to celebrate the building’s 20th birthday.   According to the paper,  when the library made its move to the new building in 1994,  children used little red wagons to help move books from the old location to the new.

The dancing is part of the Music & Movement program for kids ages birth to 5, held several times a week at the library.
