If you use this pdf for your own travel needs, know that it's officially Friendly-Ware®™, i.e. « be friendly » (send a picture, say thanks, give 'er a woof, et caetera).
And here are some shameless pictures of Duke, because, well, he's adorable and has officially teary-eye-stared my protective cynical sheen to oblivion.
