NORTH BEND — It’s 3 p.m. on a Tuesday. The last bus has pulled away from Hillcrest Elementary School. Peace reigns in deserted hallways.
Or not.
Down the stairs and around a corner, joyful noises spill from the school’s music room. Tink-tink-tink! Tonk-tonk! Tink-tunk! Marimba Club is vigorously in session.
