LAGRANGE TOWNSHIP, Mich. (AP) — Hundreds of people spent Independence Day in swimsuits but no masks at a lake in southwestern Michigan. The turnout disappointed authorities who warn that the coronavirus remains a threat. The party occurred Saturday at Diamond Lake, near Cassopolis in Cass County. The sheriff’s office said it couldn’t stop the gathering, although officers were at the lake to ticket people for certain offenses. Gov. Gretchen Whitmer’s office said it was “incredibly disappointing” to see so many people ignoring safe distance guidelines.
