Text under the picture says, "The Union High School Marching Band takes part in Saturday's Rose Festival Grand Floral Parade."
Huh. I remember band as looking more like people in unisex uniforms carrying instruments and playing and stuff, but I guess things have changed since my day.
(There is half of a flute pictured, on the right side of the picture. Also, picture caption writer, you might tell us from whence the Union High School came. Because I have no idea.)
