THE "CAB" IN CABIN – In lookout tower parlance, the single room atop the tower is called a "cab." The Smiths' cozy cab seats 12 comfortably, and the furniture and décor are intentionally casual. “Nobody feels they have to take their shoes off," Bick Smith says. A sleeper-sofa accommodates overnight guests. Cabinets conceal a mini-fridge and a microwave oven. There’s no running water and no bathroom, but a portable toilet is stationed 150 feet away from the tower’s base. Meals tend to be informal; think burgers and barbeque.
