I just wanted to let you guys in on this place... Many of you may already know of Costa Mesa's gem. But I just moved to Socal in 2010 - and am still learning my way around the area. I live in Newport Beach, and there aren't many public courses nearby - that I have found at least - that have a driving range, putting green(s) and chipping green (for free access). But Costa Mesa Country Club (it's public) has it all - and 36 holes of golf to go with it. I think this place is going to be my new 'home' once my range key at RSJ runs up? I'd highly recommend you check it out if you are looking for a place to either play or practice.
FYI... Twilight was $30 for 18 holes - and the walkability was 8/10.
