Every year, 6th graders at McKinley Elementary School study the Underground Railroad. In March, as in previous years, the students attended a four-day camping trip.

During the outing, school supervisors engaged the students in a re-enactment; however, one parent says it was not a positive learning experience and left her daughter upset. The school calls it a misunderstanding.

“All the black kids were slaves and all the other people were white,” says Dawn Peterson, a parent of one of the student’s who participated in the lesson.

“For anybody, for any tragedy that you go through, you can overcome, don’t stop. That’s what they got from it,” explains the school’s Principal, Jerome Ferrell.
