Great Yarmouth’s famous rows run East to West and channel the health-giving sea breezes. Those “breezes” helped to fight off the Black Death when it hit in the years 1347-1351, killing a third of Europe’s population. Those wind-channelling rows did a pretty good job of cleaning away other diseases in the ensuing centuries.
But now, those very rows are a problem. They’re not six-foot wide. Some are barely 4-foot. How do we social distance in that?
