My e-chum, Suburan Diva, has partnered with Hebrew National for Picnic with a Purpose. Ok, I don't know how formal this arrangement is, but the idea is great. However, I'm finding bits and pieces about this around the web.
Anyway, the idea of an informal gathering, with friends and family, to raise funds, gather gifts, or otherwise pitch-in and help out the community is wonderfully gracious. This, really, is something I must try to make happen, too.
