I was raised in the Plymouth Brethren religion at Greenwood Hills Gospel Chapel in Fayetteville, PA (south central PA).  We were an open assembly (yes that is what we called ourselves) and we associated with other open and "closed" assemblies in the U.S. (most on the East Coast and Ohio, Indiana, and Iowa).  Greenwood Hills is an active Camp and Conference Center for those that are interested in learning more.  Most of what I have read here is correct.  Women are not allowed to speak during the Lord's table and headcoverings must be worn.  Please go to www.greenwoodhills.net for it is my generation that has brough the brethren on-line.  Unfortunately the strictness and backwardness of the church has caused many young people to leave.
