When I was young and we would walk on the beach of the Oregon Coast, I was told to never, ever turn my back on the sea. It wasn’t a rigid rule, despite the vehemence with which it was given. The rule was more of a guideline; imagine having any kind of fun at the beach trying to keep a constant watch for tsunami or rogue waves. Instead, the idea was to never take geography for granted. Keep an eye out in every direction.
