Erin,
I don’t know about how many CM users there are in Lansing but there are definitely lots of homeschoolers. Maybe you already know that. CHAP is a community group there. I think you could gain some info from them. I live on the southeast side of GR but have some friends in Lansing. We have gone to the Homeschool performing arts plays in Lansing and judging form the size of the cast, there are oodles of home educators there.
April we will pray for peace in your decision making. Congratulations on your beautiful children. There are many people here too who adopt children from other countries. And congrats on finding employment here. That is not so easy these days.
