Around 1:00 this afternoon, after all the flights had been cancelled, I looked up to see something rare in Vancouver: a cloudless, warm, blue summer sky without a single plane in it.
Fifteen minutes later, I heard the sound of a jet. Puzzled, I sought it out, and it was another rarity here -- a lone military fighter, flying straight and level, east to west, surveying the city.
It disappeared and the sky was quiet again, and I walked again, to take my oldest daughter to preschool.
