Let’s Celebrate! Celebrate the accomplishments of Thunder Bay National Marine Sanctuary (TBNMS) as we expand to protect the Great Lakes and their rich history. This has been an absolutely incredible year for the sanctuary, and there are several exciting developments on the horizon. The Friends of TBNMS invite you to a Sanctuary Celebration on Saturday, September 6 at 6:30 pm. Join us at the Great Lakes Maritime Heritage Center for live music, cash bar, and hors d’oeuvres. Purchase tickets in advance for $50 each at the Sanctuary Store or call 989-356-8805, ext. 18.
