The happy art on the hill was created to put a smile on Nevada County resident faces. Every month we change the theme of the happy art. The majority of this hill side art was based on drawings by the grammar school children of Nevada County. This was part of a contest where over 300 children from Grass Valley and Nevada City participated in a drawing contest. There were hundreds of dollars in prizes and art supplies given to the Grass Valley and Nevada City grammar schools. And to this day, parents and children look for their art on the hill.
