Take a field trip and explore the Presidio Tunnel Tops, including the Field Station, where you can get hands-on with nature specimens, artifacts, tools, and maps. And Sendy Santamaria, author and illustrator of "Yenebi's Drive To School," will be leading an art workshop and taking us to some secret and not-so-secret reading spots in the Presidio. 

Space is limited and advance registration is required. Stop by Excelsior Branch Library to reserve your spot.
