You night have imagined that these kids are in detention serving time for some misconduct at school. Former Principal of San Pedro High School played no jokes with unruly students and raking streets was a form of disciplining those few.
But no, these kids were not in detention. In fact, they were on a mission of love, raising funds for their high school by way of a work-a-ton. This picture was taken in 1977 when funds were being raised for the construction of their new building. Therefore far from being in detention, these early high school kids were willing volunteers on a mission of love to construct their high school building.
In this Flashback picture you see the cleanup taking place on the north end section of Middle Street (now Pescador Drive) in downtown San Pedro. Below is a picture of how that same street scene looks today.
