Tens of thousands and more every day volunteer for our city's great nonprofits. As a tribute to these folks, we've created a multi-hearted poster.  Count the hearts and "heart parts" on the poster below (they're not all so easy to find!), email the number you find to jgpizzoli@ComingofAge.org (our poster designer), and if your entry has the correct number, you'll enter a drawing to win a $50 Barnes & Noble gift card. Entries must be received by January 15, 2007.
