Some mostly modern style trio's which I don't claim to be the equal of Southampton or Pebble, but they'd be interesting combinations:
-Golf Club of Scottsale and two courses at Whisper Rock
-Rancho Santa Fe, The Bridges, and RSF Farms
-Mauna Kea, Hapuna, Mauna Lani
-Shadow Creek, Wynn, Cascata
-Dinah Shore Course, PGA West Stadium, Plantation
-Bighorn, Stone Eagle, The Quarry
-GC of Austin, Austin CC, Barton Creek (Crenshaw or Fazio)
-Oak Tree, Karsten Creek, Southern Hills (2 hrs of driving)
