Pros:
Black Diamond is very tough, from any layout you choose. With four sets of tees, you can trim some length off of the course, but you are still looking at a par 70 or 71. Not a course that is beginner friendly. There are tee signs showing all tee positions, pin position, distances, Tee boxes are differentiated by color coded markers in the ground. Elevation changes are fantastic, water and woods are formidable, and all shots will be needed.The baskets were all in ok condition. I played the white tees, and shot a 5 over par (75). Red tees are shortest, then whites, blues, and gold the longest of all. I thought the entire front 9 was great, and 10, 14, and 18 as well. The others were not entirely without charm, either. Hole 1 is crazy, a swerving 40' wide ski run downhill with heavy woods lining both sides much of the way. White tee is listed at 934' and I pulled an awesome second shot with my roadrunner, to make an unlikely 4. 2 is another tough one, with water behind the basket. Woods are heavy, and elevation climbs through the rest of the front nine. 10 is across the street from the parking lot. The back 9 loops around another part of the park, and is a little more open, but just as challenging. 14 was a cool one downhill into woods near the edge of a stream. 17 has a very large, odd mound protecting the basket. 18 is just a good hole through beautiful old trees. This is surely one of the most challenging I have ever played. An incredible park with things you won't see in most disc golf courses.
Cons:
I parked in the wrong place, near the tee for 14, and picked up with a couple of guys from there on the final 5 holes. They gave me some much appreciated tips on the rest of the course. It was a total pro they helped me out, but I did have trouble finding the beginning of the course. A map for the course can also be very useful. Some weird transitions between holes. Rough can be brutal in places, and water might get you too.
Other Thoughts:
A very serious challenge. Don't go if you want a quick round, or you get frustrated easily. If you like what you're reading, the go, by all means. It is a course with lots of personality, and a favorite of mine after playing one round. Emery Park is pretty cool, I loved seeing the ski lift, waterfall, and several other points of interest and/or natural beauty.
