Locating the book's drive-throughs

Here is a map that shows the approximate locations of each drive-through that is in Driven to Espresso. As you can plainly see, the majority are in the Puget Sound region. Admitedly, I spent the most amount of time in and around my own "backyard" which is the real reason for this, but I want to go on record as saying that Portland and Spokane, especially, have way more drive-throughs than what you might guess from this map or the book, and in fact, I actually visited and photographed many of them. There were several reasons for limiting the size of the book, but not having enough espresso stands to choose from was not one of them.
