Zandes--Try your local library and, possibly, the local health-food store. We are religious but not what you'd call fundamentalists, and we had trouble finding homeschool groups that fit our outlook. We homeschooled at a time when it still was not so well accepted, and we never really found a single group we'd term "our community." We made up for it chiefly by just sticking with pursuit of the kids' personal interests. Gradually, the kids met people they enjoyed--one via art classes, the other via horseback riding activities.
Dispite the lack of "community," both our kids swear by homeschooling and plan to homeschool their children. When you think about it, there's really no absolute need for kids to associate only with other kids. There are advantages to having friends in all age groups. (Of course, you want to keep a close eye on things.)
Our local librarian says they have tons of homeschool associations visiting the library all the time. That's where I got the library idea for you. The one about the health food store I remembered from our homeschooling days. We have a wholefoods co-op in our area, and they maintain a bulletin board. It occasionally has info on what might be called "alternative" homeschool groups.
