There's a village up on the north arm of the Millsport archipelago where, if a fisherman survives drowning, he is required to swim out to a low reef about half a kilometre from shore, spit into the ocean beyond and return. Sarah's from there, and once, holed up in a cheap swamp hotel, hiding from heat both physical and figurative, she tried to explain the rationale. It always sounded like macho bullshit to me.
