Vivian and I live in the biggest city in South Carolina. (Our daughter and grandchildren live in the next county.) But SC is not heavily populated, so our county has only about 1000 cases. Beach communities have lots of visitors, so the virus spread more widely along the coast. Meanwhile, my brother lives where we grew up, southwest of the “big city” of Atlanta (which is a darker red than the city where I live). But his town is far enough away to avoid a lot of the sickness.
