Today’s Remember When “mystery photo,” at top left, shows students at a local elementary school calling attention to a special week at their school in February 1981. What was the school and the occasion, and who were the students?

Last week’s Remember When “mystery photo,” at bottom left, shows an abandoned oil tank burning in September 1974 near the corner of Tracy Boulevard and Beechnut Avenue. The fire was started when an acetylene torch used to cut holes in the base of the 160-foot-diameter empty tank ignited residual crude oil in one of the wooden poles that had supported the wooden roof.

The location of the fire was the original Associated Pipe Line oil-pumping plant, later operated by Getty Oil Co. The fire broke out when the tanks were being dismantled. Because of oil-contamination problems at the location, the property remains undeveloped today. The photo was taken by Gary Patterson, a local photographer.

Identifying the location were Dan Schack, Dennis Maddox, Ray Fragoso and B.J. Hernandez.
