Take a walk on Children's Avenue and watch youthful creativity at its best. Children's Avenue reserves 1,500 small "squares" for the littlest talents of our community: kids ages 2-12. Some families consider the creation of a "square" on Children's Avenue a "requirement" of growing up in the Bay Area. For only $12, kids are assigned a 2'x2' square and given a box of pastels, a blending eraser, and a Polaroid photo of the finished painting.
