Played Saturday 5/19. The greens were recently aerated. No notice given on the maintenance. It made a very difficult time putting as the greens are very bumpy and slow. I would like to play here again after the other half is aerated and the greens have recovered.

Noise from freeway catches you off guard at first, but if you don't think about it and just play, you'll be fine. Started about 15 minutes late and it took just over 5 1/2 hours to play.

Good Customer Service.
Some of the greens were a little bumpy here and there. #18 green has some major issues. Besides being soft, a lot of patches makes it very difficult to make a putt. You have a better chance to make a putt on an aerated green.
Some holes have roughs that are patchy and have areas similar to deadpan. But mostly, good thick rough to give an advantage for the more experienced player. Have a good idea where the ball lands because it can be hard to find at times.
Considering the price, the drive and a 5 hour 20 minute round, I would rather play in LA or in OC.
If you are driving back to Orange County on any night, consider the drive as it took 1 hour and 45 minutes to get back home on the 15 and 91.

I would give the greens another week to be back to normal. Greens were still soft, slow and bumpy in spots. The fairways were ok and seemed to have more bare spots than usual. I have seen it better and hope the fairways improve in the upcoming months. The rough was good and thick. I agree that the rough should penalize you if you can't stay in the fairway. Tee boxes were recently punched, but no big deal since you can always find a spot.

I can't believe that we were able to finish in under 5 hours on a Sunday. We had to wait on the tee on half the holes and sometimes on our approaches, but not too much more than that.

Ballmarks galore!! Extremely slow play. What has happened to this course? I played several months ago and finished in about 4 1/2 hours. Played on Sat at about 2:15 pm and finished a little after 8pm.
If you are going to charge us more than the other LB courses, then provide better service.

Slow and bumpy greens. I can't believe they charge $25 per cart during normal hours. Thankfully I am not a regular up there.

The course and greens are in great shape. Course played a little slower than normal, 5 1/2 hours. Just thankful that the pace picked up after #7, otherwise it would have been a 6+ hour round.
I highly recommend a hot dog or hamburger after #7...always tasty....but watch out for the birds.

Not a bad course for what you pay. Tee boxes were good, fairways good with some bare spots here and there, and greens a little bumpy and slow. The round plays slow (5 1/2+ hours) on weekends.

They definitely need more help in the clubhouse. One person to do everything is not enough. They try to squeeze in all the people on the waiting list at the last minute. Expect a late start from your tee time, at least 15-20 minutes. A reminder to the cart girl, it is an 18 hole course, not 9. I saw her 3 times on the front and at the turn. No sign of her on the back at all.

Course in good shape. Greens a little slow (normal for the course). Only had to wait 30 mins on Sunday as a walk-on. Tee boxes, fairways, and greens are in good shape. First time playing the new holes on the Back 9. I liked the new holes.
