For me it would not be a "course I could play every day" but rather a "course I would play every day" and at a minimum the course should be of sufficient quality where one would be willing to forego rounds at other venues. Would you be willing to give up the once a year trip to Friar's Head or Winged Foot?
I mention "would" because though design wise Rustic Canyon is a delight, who can tolerate a five hour round? or too many mandates with carts, caddies, tee times, or an over the top clubhouse or locker room or even halfway house?
For me, perhaps because it is such an anomaly in the New York Metro area and far from "top 100" status (I have seen rankings that do not have it in the top 50 Met) Rockaway Hunting.
