Old Macdonald (No. 43 U.S./No. 74 World): Bandon Dunes Resort's fourth course might be its most distinctive and its most fun. Architects Tom Doak and Jim Urbina managed to pay homage to pioneer American architect Charles Blair Macdonald and still build a one-of-a-kind seaside treat that is unlike nearly any course ever seen. Massively wide, rumpled fairways and putting surfaces that Doak labeled "probably bigger than any set of greens anybody has built in 30 years" still demand thoughtful placements and proper trajectories, as the crunchy turf and frenzied contours will funnel marginal shots in unexpected directions. Solving such puzzles is the enduring joy of Old Macdonald.
