I 'spect the reality is:
The Manistique boardwalk project was funded, primarily, by tax money from productive entities near and far. The Manistique Downtown Development Authority provided initiative, planning, intellect, concern, dedication, accountability, etc., but chances are, it neither earned nor funded one "red cent" beyond the personal tax contribution of each member.
With focus on contributors, responsibilities and accomplishments, someone else might have said, with appropriate editing:
"This project is funded and maintained with taxpayers' money and was conceived and realized by the dedicated individuals that comprise Manistique's Downtown Development Authority."
It would have been far more honest and less convoluted than an apparent paean to DDA egos.
