The King Street Center of Burlington celebrates its 40th anniversary this year, and supporters are marking that milestone with the 40 for 40 campaign, which aims to send 40 of the center's kids to Camp Hochelaga or Camp Abnaki this summer. The Zahniser Camp Fund Committee, founded by former Champlain Elementary School principal and community leader Nancy Zahniser, is organizing the effort. King Street's after-school and mentoring programs serve more than 500 neighborhood children each year. A few of them have made a YouTube fundraising video in which they sing camp songs and describe their past outdoor experiences in humorous detail. They talk about activities they tried for the first time at camp — such as windsurfing and rock climbing. The most important thing to pack in your knapsack? "Bug spray," they say. Donations to the Zahniser fund help make the experience possible; a donation of just $125 can send a child to camp. Find out how to donate on the King Street Center website, kingstreetcenter.org.
