Pros:
The Murrieta course is not your typical green fairways and wide open shots. The course presents refreshing obstacles between you and your par score.
For advanced players, the course offers multiple levels of difficulty that include blind shots, unpredictable wind conditions, long basket positions, and technical shots. If you have played the courses in socal the course seems to be a mix of Brengle Terrace and Huntington Beach. The local club has added multiple pin positions so if you play the course a few times a month you will play different layouts often.
The course has a few holes where you can let loose and bomb your discs (a couple 400+ft and an almost 500ft). You'll almost certainly find yourself using your technical skill to layup or get out of the rough--which there is a good amount of.
If you live in SoCal and play disc golf you should be able to say you played Mountain Pride. Even better if you finish under par.
Cons:
While it's a fun course for both beginners and advanced players - beginners can get caught off guard if they try to play from the long tee pads. Highly suggest starting from the short pads and getting used to the course layout and basket positions.
For those who are older and want something more level, this course could be hard on you. The course provides a hiking-like experience and you will go up and down a few times.
Other Thoughts:
There is a map near the baseball field posted on the board for people new to the course. The worst thing you can do is start at the wrong pad and start throwing. You will lose a disc or two. This is the only complaint I've heard about the course and typically it's from people who don't know which pad to throw from. The course is a challenging one and if you don't have the arm to throw then start from the short pads and have fun!
