GRAND RAPIDS – About 450 river advocates convened here this week for River Rally, an annual conference hosted by River Network. “Coming into 2017, we knew we wanted to do (the conference) in the Great Lakes region, and Grand Rapids had a great river story to tell with the restoration and revitalization of the Grand River,” said Alice Srinivasan, director of community engagement at River Network. Srinivasan appreciates the opportunities the conference provides each year to hear stories like those from Standing Rock.
