Pros:
The first thing I noticed was that this course is separated from the rest of the park by quite a bit of distance. There is a sizeable walk to get to it from the parking lot, so the only people you see on the course are disc golfers for the most part. There are the occasional bike riders on the path leading up to and going through the course, but I have never really seen them causing any issues. The course itself was very well designed and is located on a beautiful piece of land. Tee pads are in great condition, some being recently replaced, with good signage and brooms and fire extinguishers at pretty much every one of them. All tees have at least one bench, but most have multiple benches or chairs of some type. There are multiple pin locations for every hole. Great use of elevation throughout the course. Each hole uses the natural terrain very well and no two holes feel the same. The course is spread out over a large area so you won't have to worry about crossing fairways too much unless you really shank one. This course is very challenging and gives you ample opportunity to use every shot and disc in your bag. A true equal opportunity course. Righty or lefty, backhander or forehander, no one throwing style is favored on this course. In fact, to do well on this course would require virtually all throwing styles, including overhand.
Cons:
The infamous "Napa Roller". Although I really consider this part of the challenge and not necessarily a con, there is some frustration to be had when otherwise good shots hit the ground and roll down the hill farther than where you originally threw them from. Due to the elevation changes throughout the course, one can get winded going up and down the hills all day chasing frisbees. Then there is that long walk back to the car when you're already tired from playing your round.
Other Thoughts:
Bring plenty of water and snacks (I suggest trail mix). You will be tired, hungry and thirsty during a round here so be sure to bring these items with you. Also, I forgot to mention that they sell discs in the little kiosk at the front of the park. The prices actually aren't too bad. There is a practice basket right next to the parking lot and bathrooms. I like to practice putting while waiting for friends to arrive, so I find this rather convenient.
