I was sitting in the physician's waiting room this evening and watched the WDIV coverage. They were talking about roadblocks in Macomb county (for other readers, northeast of Detroit, north of Lake St. Clair) and in Trenton (south of Detroit and Windsor, with only the narrow Detroit River). I don't recall specific statements, but there was the implication that these random roadblocks will continue.
For everyone's reference, if the law says roadblocks can go up within 35 miles of the border, then that's way out past Ann Arbor; Chelsea and Adrian are about 35 air miles from the border.
