Northborough – (l to r) Third-graders Lauren Theve, Olivia Lamy and Daniella Martens prepare to climb up the amply snow-covered Mount Proctor for another round of sledding during the 11th annual Winter Carnival, held at Proctor Elementary School. The evening of family fun featured a ziti and meatball dinner, horse-drawn wagon rides, music provided by a disc jockey, karaoke and face painting. The longtime seasonal tradition for students in kindergarten through fifth grade is sponsored by the Proctor Papas.
