Artistic Tanks From the infinite fount of weird Americana comes a really great collection of painted tanks. Some are downright clever, such as Blaine County, Oklahoma's Cow tanks and the Watermelon tank. Many are appealing in a sloppy, amateurish way, like the Smile tank and the goofy Face tank. And some are unintentionally disturbing -- witness the eerie Clown tank of Clark County, Ohio. But most will elicit a smile or two. (in Travel)
