Some cities have inner pockets that feel like worlds unto themselves—little enclaves that are either well-hidden, little-known, or inaccessible to the general public. The perfect example is Seattle’s numerous houseboat communities. I’d been dying to sketch the houseboats ever since I moved here, and on Sunday, I finally got my chance. Every two years the Floating Homes Association organizes a public tour of a handful of properties—but doesn’t exactly broadcast the event. After years of missing it, I finally scored tickets—which, to Mary-Alice and I, felt something like passports to Narnia.

Not only did we get to see the sights and meet friendly folks—

—but we also got what felt like a slice of a parallel universe.
