Blue Water Indivisible hosted a Flag Day celebration Saturday at Pine Grove Park in Port Huron, drawing about 400 people. Though tied to the national “No Kings” movement, the event steered clear of protest, focusing instead on community and patriotism. Attendees enjoyed music, kids’ games, a food truck, and an open mic for sharing personal stories. Organizers encouraged picnics and used the event to raise awareness about their group’s goals.
