Peace groups are asking constituents to contact their members of Congress this week, as most come home during the current recess, to advocate ending the Iraq war and bring the troops home. More information here:

Efforts are also well underway to organize marches and peace vigils on or around the anniversary of the start of the Iraq war. There's information on various efforts from United for Peace.

Sojourner's magazine provides a couple of useful services: you can search for a scheduled demonstration near you at this site, where you will also find ideas on organizing a peace vigil where you live.
