Rustic simplicity is rare in the bed-and-breakfast world of lacey curtains and Victorian architecture. Sitting on a 17-acre wood just north of Kansas City International airport, the Dome Ridge B&B is not a gingerbread house -- it's a geodesic dome. One suite has a private deck where guests can take a steamy late-night hot-tub soak while stars and airplanes twinkle beyond the trees. In the morning, Bill Faust whips up Belgian waffles and sausages and whistles Johnny Cash tunes in the kitchen while his wife, Roberta, chats about the four cats who live in special, heated cat houses. Dog people beware: Kitty knickknacks abound.
