GNOMES at work: Gloria Towle-Hilt, left, measures lumber while building a home-improvement project as part of a Christian work camp. Towle-Hilt is now helping to organize a local camp, to be housed at Guilderland High School next July.  The St. Madeleine Sophie youth, who have participated in service trips across the Northeast for the last four summers, call themselves the Guilderland GNOMES, which stands for Giving Neighbors Our Meaningful, Enthusiastic Service.
