Trefoil Neighborhood Girl Scouts Megan Morrow, Caitlyn Houser, Jess Kimbell, Joann Ow and Miranda Huber, all from Senior Troop 847, and Daisy Scout Julia Ow from Troop 464, raise money for needy families in the Mars School District during Caroling for Mars at Giant Eagle in Seven Fields last year. This year, scouts again will collect tonight from 4 to 8 p.m. and Saturday from 9 to 3 p.m. and 6 to 7 p.m. at the Foodland in Mars and from 4 to 9 p.m. Friday and 10 to 6 p.m. Sunday at the Giant Eagle in Seven Fields. Last year, the girls raised more than $3,000 and bought presents for eight families, which included 27 children.
