There was some discussion a while back about a coalition of suburban leaders [[mayors, state reps, councilmen ect…) that supported transit oriented development along Woodward. It was in the context of light rail, but nevertheless, does anyone remember what this group was called and who the principles were?

I believe you're thinking of the Michigan Suburban Alliance.
While the Michigan Suburbs Alliance is a part of the group and is participating in planning activities, the Woodward Avenue Action Association is actually heading up the initiative.
