Sunshinemama did a wonderful job with the "Mothers for Peace" website, she keeps adding more links and articles.
In Chicago I have been somewhat active with a group called Peace Response and I participated in a few meditations and prayer groups. I'm not genearlly one to participate in protests, so I haven't done that. A friend here in Chicago is forming a local group of "mother for peace", but it is very fledgling.
Anybody who wants more info, let me know...
