Rob said, "There was a rumour about 7 years ago of La Purisima being considered for the US Open. The nearby Pea Soup Anderson's and the "Sideways" motel would need a wee bit expansion to accommodate out-of-towners."
Great understatement of all time ! 
Lompoc, the home of LaPurisima could host even more people if they could use the Federal Peniteniary !
All kidding aside -- LaPurisima is a superb layout that often gets little attention -- why Sandpiper is rated higher in many instances baffles me but it's likely because the course in Goleta is closer on the beaten track and just outside Santa Barbara.
How I wish there was a way to get to LaP faster. Never a wasted day when playing up there, but it was definitely a full day's affair even from SB. I've read somewhere that the owner is trying to develop the property with a hotel to cater to the wine lovers. It would be a shame for one of the most unspoiled tracks in SoCalish to not be so pristine. But worse yet, a modified LaP for development would be a shame.
