Nope! I remembered a meeting happening in Ann Arbor but it appears that was a once-off thing, as I can't find any links to a group based there. Not to mention I couldn't make it there anyhow, anytime soon.
There are meetings in the area every couple of months. There's no specific group to link to, but if you give me your email address I will add you to the list.
If you tell me where exactly in Michigan you are, I can try to put you in touch with other Michigan LW/SSC readers. Most are in Ann Arbor, but there are several in the Detroit metro area and at least one in Grand Rapids.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
