  The local name for the grey, cool weeks that sit on the city between late May and the Fourth of July, when the marine layer refuses to lift and everyone insists summer starts later here.

• 自然

  Salmon at the Ballard Locks

  The Saturday nearest the solstice, and the one parade with rules against motors, logos and printed words of any kind. The body-painted cyclists ride ahead of it and the bridges into Fremont clog from late morning. 來源 ↗

  Bumbershoot
