Was your school playground lined with murals? It was if you went to Davis Bilingual Learning Center, 500 W. St. Marys (at Granada). This artistic school is one of the many bright spots you'll find around this arty corner of Tucson, nestled against the east side of I-10. (Check the mural table to find more of them.) Thanks to the students, mentors, the Barrio Anita Association's mural restoration program, and a mural grant from the City of Tucson.
Though the gates were open and no one was around during the early morning time I was there, you might want to check with the school office (520/225-1400) before you come on your own tour.
