Vancouver, City of Worm Enlightenment
I don't know what it is about the Pacific Northwest and earthworms, but these people have really got it going on. They even offer suggestions for a "dog waste" composter, although they are careful to point out that there is no finished product to be used in the garden. The goal is to create more of an underground digester that you can deposit the little treasures in. Not much to do with worms, but the point is that they leave no compost pile unturned.
