Our dog Sonora, who is about 17 months old, is one of the sweetest and most tender dogs I’ve ever been around. We named her after the heroine in the film Wild Hearts Can’t Be Broken. Like that character, Sonora can be shy and tentative, but her hesitation belies a kindness and a depth to her personality that defies description. We’re lucky to have her and her sister as part of our pack, even if she acts a little strange (above) whenever I give her a dog biscuit. She usually hides while she eats it so her sister, Layla, a rambunctious sweetheart named after Muhammad Ali’s prize-fighting daughter, doesn’t come after it. Good call, Sonora.

MIT student Ben Fry has developed a very cool ZIP code map that lets you view the area assigned to each number of your ZIP code (3-7-2-0-9, for example). It looks like a star-filled night sky shaped like the United States. Click once on the map and then type in your ZIP code one digit at a time and watch it zero in on your homebase. It won’t reveal your rooftop or anything, but it is interesting to see how ZIP codes fit together. If you’re looking for a little perspective, hit 372 (the Nashville area) and zoom in.
