Pros:
The Santa Cruz Mountains rising up above the central coast are innately beautiful, combining very rugged hills, mountain streams, and giant redwood forests. The communities are quaint and cute in the small town way, with a mountain refuge-like feel. Many organizations have getaway camps in this region, for good reason.
San Lorenzo Valley has several schools bunched together on a very large sprawling property, which includes some rather beautiful redwood forest-covered hills over-looking all the campuses. It is a wonderful thing to be able to install a disc golf course on this property, as it is yet another ideal setting for our sport.
When locals in Santa Cruz say that we have every kind of course and disc golf hole imaginable, we aren't joking. Black Mouse is the rugged, tightly-wooded, technical course of the Santa Cruz area collection of disc golf course. There are simply no holes that having a big arm will help you score better. Throwing with a nice careful clean snap is key. Shot and disc selection are critical Only holes 7 and 11 require more power if you have any hope of getting a deuce, but just getting a 3 on these holes will be satisfaction enough.
The first time you play Black Mouse, you won't know all the routes available, and you might be tempted to start with the impression that this is just a "huck and good luck" kind of course. But it isn't true. There are many interesting routes and lines available on most holes, you just need to play it a few times to learn the ins-and-outs, then choose the one that you can execute best, and that gives you the best risk-reward trade-off.
Cons:
The tee pads are indeed irregular in some places, and the dirt pads are often not the greatest to throw from. However, given that the course is not long, you really don't need a run up to throw on any of the holes. If you're concerned about footing, just throw without a run-up, and you'll be fine.
The restriction to non-school hours can be a hassle sometimes, but that's not a bad price to pay for having them let us onto their property in the first place.
Other Thoughts:
I printed off a map of the course from the google maps link, and I didn't have any problems finding every hole on the course the first time around. I also found a lot of signs pointing to the next holes. Perhaps these weren't available when some of the earlier reviewers played this course. The course is not crowded, so you won't be able to rely on other groups to help guide you as much as you could at other courses. Come prepared, and you'll be happy. Also helps if you're not in a huge hurry, and take a minute to relax and enjoy the gorgeous redwood stands all around you.
Come out for Sunday morning doubles here if you get the chance. A lot of the pro women players in the region play these dubs, and you can see how regulars choose their routes and score well in this tight course.
