Lauren Chadwick, 10, left, and Grace Wilson, 10, of Girl Scout Troop 28842 sing Christmas carols and collect donations Saturday morning outside of Dave's Country Meats in Middlesex Township. The Girl Scouts also sang and collected donations at Mars Supermarket over the weekend. The money raised will be used to provide Christmas gifts for children in need. Santa and Mrs. Claus stopped Sunday in Mars for the borough's light up night festivities and greeted participants at a bench beside the town's spaceship. The event, originally set for Saturday, was moved Sunday to avoid the rain.
