McKenna, Anneka and Leilah Anderson, from left, sell lemonade Wednesday on the corner of Lowell and Harding streets in Ironwood. According to their grandmother, Kathy Anderson, the girls, on their own initiative, wanted to raise money to buy water filters for the people of Haiti, through a program run by Lutheran Church Charities. The girls learned about the cause at Trinity Lutheran Church’s Vacation Bible Study this past week. A school-sized water filter costs $185 and home water filters cost $35. Through Thursday evening, the girls had raised $70 selling lemonade and had inspired three friends to do the same. In one day, that group made $77 for the same benefit.
