I haven't seen them out here in Washington, but then haven't really looked hard, either. However, a couple of weeks ago my husbnad and I were in a town on the Oregon coast and saw one on a large dairy barn. I didn't have my camera with me, so told him we'd have to go back the next day so I could take a picture of it.
Well, the next morning we were awakened by a tsuname warning because of the earthquake in Japan and had to evacuate because our hotel was right on the beach.
Now we'll just have to go back because I really want a picture of that square. :lol:
