These are the houseboats at Clover Island in Kennewick. If you've seen the real ones you can see some liberties were taken with colors on the sketch. This sketch was done in '08, and everytime I look at it I think I could do better with another attempt; the perspective is too wonky in this one. Now that the weather has gotten nice, maybe one day next week?
