Trinity Lutheran v. Comer is a court case with humble origins. It started with officials at Trinity Lutheran School in Columbia, Missouri, who wanted to replace the gravel surface of the school's playground with something more forgiving.

This surprisingly complicated and potentially far-reaching case is the topic of a new essay by Show-Me Institute Director of Education Policy Michael McShane, which you can read here.
