Pat,
Don't worry, Pine Valley isn't alone.
I've run into just as many golfers who don't know what Cypress Point is in addition to never having heard of Pine Valley.
To get thier attention, you have to make it a regular big boy stop...like a Riveria, Pebble, Olympic!
P.S. These same folks also haven't heard of places like Sand Hills, NGLA, Ballyneal, SFGC, etc.
