As happy as a dog in the back of a pickup truck. Two dogs, actually, in the back of two pickup trucks. First, a young curly-haired teenager, tongue as far out as it could go, its mouth a wide, bug-catching receptacle. This utter encapsulation of joy was followed by another dark green pickup truck, this one hauling a thoughtful old golden retriever. With light white furry circles around both her glinting eyes, a soft smile of utter contentment was evident in her very posture.
