City of Kirkland has installed free public wifi that cover the downtown core and a couple of downtown parks. The connection is good, decently fast. I found an power outlet even!
The only problem was finding shade.
I also discovered that Wednesday's are Kirkland's farmer's market. Berries are in season and are cheap. I bought a half flat of mixed blueberries, blackberries, and rasberries for $10, and then found a sale and bought two full flats of blueberries for $36. Good for smoothes and for freezing.
