Montello Elementary School third-grade teacher Mike Parker, right, claps to the beat of musician Ian Barclay, left, as he plays the bagpipes in Parker’s classroom Tuesday afternoon. Takota Pelletier, center, does an Irish dance to the music for the class. Parker will be leaving Montello at the end of the year for the new Geiger Elementary School. Parker has been decorating his classroom and the halls of the school for the past 37 years for St. Patrick’s Day.
