To the editor: This summer, 23 New York City children found out just how special summer is in the Charlotte, Shelburne, South Burlington, St. George and Hinesburg areas. None of this would be possible without Karen Allen, your local Fresh Air Fund volunteer leader, who works throughout the year to make sure summer magic happens for host families and children. Karens generosity and commitment is an inspiration to us all. The Fresh Air Fund, an independent, not-for-profit agency, has provided free summer vacations to over 1.7 million New York City children from low-income communities since 1877.
