Pros:
The course is set in the foothills of the Sierra Nevada mountains, so there is a ton of elevation available for the course. There are beautiful old oak trees scattered throughout the course, and a few holes play through denser stands of them. Throughout the course there are great views of Hensley Lake and of the Sierras, making for a very scenic round.
The course uses the space well, playing up/down/across big hills, and using the scattered trees pretty well as obstacles. There were a few holes that required something other than a RHBH hyzer shot, so that kept the round a little more interesting. When I played, the fairways had been mowed recently, so as long as you stayed on the fairways there wasn't any issue with underbrush.
The tees were decent size gravel pads, and were in good shape for the most part. There were nice hole signs at each tee that gave distance and pin location. Once on the course, it was easy to follow, and had a natural flow without any crossing fairways or places where holes played on top of one another.
The natural beauty and solitude on this course made it one of the most peaceful places I've ever played disc golf. It is off the beaten path, so you won't run into too many other players out here, though the one player who was arriving as we were leaving was very friendly.
Cons:
When we got to the parking lot, we had to search for a nontrivial amount of time to find the first tee. A sign in the parking lot with a course map would go a long way here. The gravel pads were mostly fine, but there were a couple that were very uneven and made for treacherous footing.
Though the fairways were mowed, they still had a ton of plants with small stickers that love to get down into your shoes and socks. If you end up in the rough, it's even worse, so plan to spend the next day finding bits of the plants in all your shoes and clothing. The rough also made a great place for snakes to hang out, so watch your step (we saw three during our round).
Other Thoughts:
If you are in the area, definitely stop by and play this course. The elevation changes and the views make this course unique and fun. The local we talked to said that there are plans to expand the course to 18, and if they design the back 9 as well as the existing 9, this will be an excellent course.
The course is at a higher altitude, and has very little protection from the sun on many of the open fairways. Bring sunscreen and lots of water if you're playing in the summer or fall. I would recommend sturdy walking shoes, as the footing is not always the best.
