Giving credit where credit is due, it was Spokanite, who deserves the award, for finding little Bickleton, WA, bluebird capital of the world :-).
Here's some information, about Bickleton.

Even if it doesn't have the most bluebirds, it deserves the title, because the ratio of bluebird houses (2500) to human population (91) probably can't be beat, anywhere else.
Come to think of it, we live in the bluebird's range. I should build a few birdhouses, this week.
