Country Road (puzzle)

Country Road is a logic puzzle by Nikoli.

Rules

The square grid is divided into "rooms" of various shapes; some of these rooms contain a number. The object is to draw a closed loop in the grid, entering and exiting each room once. A room with a number must have that many squares used by the loop (a room without a number may have any number of its cells used). Lastly, adjacent unused squares must not be in different rooms.
