Looking for homeschool network/coop in Dallas/Grand Prairie area

I'm looking to join a homeschool network and would like to know which ones are available in the Grand Prairie or Dallas or Mid-Cities area. I am also interested in used homeschool curriculum for 2nd grade and under.

There is a group that's based in Grapevine but has many members through out the metroplex. Go to www.horizonhomeshoolers.com
Half price books is a great place to find used homeshool books including curriculm.Also, The Book Cover on Davis Blvd in North Richland Hills.There are also many on line resources available. Just google used homeschool curriculm.
Hope that helps. Beth
