If you live in metro Detroit, the last week probably tested your patience — and maybe your fridge. First, the heat. As temperatures rose past 100, the grid strained, and a substation in Warren failed. Thousands lost power, some for many hours. Then, just as that passed, the storms came. Friday night, winds tore through the region and dropped 80-foot trees onto power lines — and at the peak, hundreds of thousands of homes went dark. Some homes stayed dark for days.
