Groups? Yes. We have a Nor'Easters playgroup, usually in the Rochester/Lake Orion/Macomb scope of things. We also have the Detroit area Mamas' Coffee Nights FREQUENTLY, so keep an eye out for the thread for that one...it pops up to the top of the list a lot!
Not in Oakland County anymore (I live in Monroe County now), but I still have lots of family & friends there and come up often. Oak Park, Farmington, W.Bloomfield. Parents still live in Oak Park. I try and keep up with the happenings up that way too.
I every once in a while try to get a hike/excursion together. Last outing, only myself and 2 other mamas made it. I'm hoping we try something again soon.... I've been wanting to visit the Howell Nature Center (they have a wildlife rehab center and zoo). I've never been, and can't seem to find anyone to go with me. Just a thought....
We should try to get a Nor'Easter's playgroup together again, soon, too. It's not LIMITED to the northeast corner of south eastern michigan...we usually have a mama up from PLYMOUTH, so you'll all be invited! I'll see what I can do to get one together in the next week or so.
