You might want to check out http://www.peachonline.org/ if you don't mind something in support of Christianity. If so you might Google it for something in Plano. I know of a few home school playgroups in Plano that are great. Also there is a home school book fair that comes in August (very soon) in Plano if you would like to be able to check out some different curriculum and listen to some speakers to learn more about homeschooling. http://www.nthen.org/
