I couldn't find a whole lot of information about this school except that it was called the Columbia Street Elementary School, it had a total of 206 students with 14 classroom and closed in 2006.
Maybe a kindergarten. Odd a little country town school had beautiful stain glass windows of the pyramids and world globe. I'd like to get those. Meth addict sort of place until the sheriff showed up.
Elementary School would be my guess. Little Acorns was on the wall behind what looked like a stage and that's more in line with smaller children. Cool explore, glad you shared it!
