I live on the other side of the state but head over the for a few weekends each season. Rougher (hilly, rocky) than the western side of the state but I really like it - really nice primitive campground. If you are thinking of relocating to the area, Brighton is just around the corner as well (and there is a competitive trail ride held there each spring).
Check out www.gldrami.org for details on ALL the distance rides in Michigan. Most are on the other side/northern part of the state but would still be within easy distance of that area.
I can also put you in touch with the ride manager of the Brighton CTR as she and her husband live near there.
