I will miss Malibu CC. One of the first "destination" golf courses because it was in the middle of nowhere and you had to seek it out. Started playing there while at Pepperdine when it was a nine hole and "private" as a tax dodge for the Perfect Liberty "church". Fun to play and 9th which became 18th was unique all downhill long par four with chapparell on both sides. Water costs closed the course. May be reclaimed.
Lake Elizabeth was another course closed by water costs in the middle of nowhere in the Angeles National Forest. Fun course that you could play on a weekend without a tee time an hour away from the San Fernando Valley. Still may be reclaimed.
Eldorado Hills Golf Course was an RT Jones Sr. executive course 18 holes par 61 hilly track and was the best pitch & putt course I have ever seen next to Incline Village. Was supposed to be turned into athletic fields decades ago but remains vacant .
Stephenson Ranch hosted a King's Putter and had some interesting GCA but was too far away from everything to make it. Turned into farm land.
