Here’s a rather unusual back-to-school letter.

It was written by Superintendent Mark R. Cross to the parents of students attending Peru Elementary School District 124, which serves the community of Peru in north-central Illinois with three schools: Northview Elementary School (grades PreK – 1), Washington Elementary School (grades 2 – 4), and Parkside Middle School (grades 5 – 8). There are about 1,000 students in the district.
