Dubsdread, once the championship course for the PGA's Western Open for a number of years. It was originally designed by Dick Wilson and Joe Lee as a traditional parkland style course, and it matured into a classic layout over the years, and recently opened after a renovation by Rees Jones.
The #2 course, The Ravines is a parkland style as well and opened in 1929, with a routing that has tree lined-fairways, ravines, water, bunkers, and smallish, fast and undulating greens.
The other courses here are good solid layouts, always in great condition, with lower green fees.
