Pros:
OVERVIEW: This course is grand on a scale that dwarfs human endeavor. One does not "conquer" Casitas: one survives it, endures it, and becomes a better person for having played it.
DETAILS: The setting is pure coastal California. Huge grass-covered (probably long & dry in the summer) hills, spectacular views, an abundance of nature in all directions. Nearby Ojai is an artist colony / tourist mecca where non-golfers can enjoy [fill in the blank - it's all there]. The course itself occupies a very small part of a very large campground / nature area that offers multiple opportunities for fun, including boating, fishing, hiking, and generally communing with the great outdoors.
Course design was probably a challenge: how do you fit 18 holes into a scene that it seems could easily support 36 without getting boring? The end result shows a lot of thought by people who know the game inside and out. You have uphills, downhills, a TON of mandatory shot-shaping, some uber-fun holes (#4 comes to mind immediately, with its crazy through-the-hole mando), and fresh surprises around every corner.
The day I played was right after a huge rainstorm moved through, which meant that not only was the course itself a challenge, but the gusty, swirling wind and residual water on the ground just added to the fun factor.
Mechanically, the course was perfect. Baskets in good shape, signage excellent (including really nifty pin-position indicators), concrete tee pads placed well, in good shape, and surface-rough for traction. One MAJOR plus was the benches at every tee - those hills enforce the need to take a load off!
Cons:
The only real "con" was the trash cans, bathroom facilities, and water, of which there were not enough. Ten bucks to get into the park is steep but totally fair, considering the multitude of activities available for the whole fam dambly. (If DG was the only thing there, it would be a bit of a rip.)
Other Thoughts:
All in all, you play this course and you know you've had an experience to treasure for a lifetime. It's not really comparable to any other So Cal course except maybe Wrightwood (or whatever they're calling that now) - an epic destination to travel to from wherever you happen to be sitting right now.
