Annually, on the first Sunday in October, LIFE CHAIN (http://nationallifechain.org/) invites the churches in each city and town across North America to stand on a designated local sidewalk and pray for 90 minutes, while holding an approved pro-life sign (http://nationallifechain.org/) The National Life Chain Sunday lines U.S. and Canadian sidewalks with a prayerful and peaceful public witness that is an extension of Sunday morning worship. This 2011 press release (http://lifechain.net/2011LifeChainPressRelease.pdf) is compelling reading.
