Always wanted to put a flock of pink plastic flamingos on someone’s front lawn? The Melrose Education Foundation can make it happen. The nonprofit, which raises money for the public schools, is sponsoring Join the Flock through Oct. 30. For a donation, the group will send a flamingo flock — small, large, or jumbo — to a home. The group hopes to earn $2,500 from the flamingo fund-raiser. To order a flock, go to www.MelroseEdFoundation.org.
