This week’s Remember When “mystery photo,” at top, shows two city officials conferring in the 1970s. Who are they, and why were they meeting?

Last week’s Remember When “mystery photo," at bottom, showed the Tracy Plunge filled with swimmers during a hot summer day. The pool was built on Holly Drive in 1931 as a private venture by C.B. Wightman of Byron. Several years later, the pool was purchased by the Tracy Elementary School District, which used it for swimming lessons and operated it for recreation in the summer. In 1952, the new Tracy District Recreation Commission took over the summertime operation.

“The Plunge,” as it was called, was closed in 1984, when the community pool in Dr. Powers Park was finally opened after a delay of several years. The wood-frame locker rooms and front reception area of the Plunge burned down in 1998. The property on Holly Drive is still owned by the school district, which uses it for storage.

Among those remembering the Plunge was Charlotte Parker Junqueiro, granddaughter of C.B. Wightman.
