Pros:
(1) Course layout is quite good. An enjoyable mix of 12 holes to play in a well-kept prairie setting with wooded areas around the perimeter. Distances vary from the accuracy-required short trio of holes in the wooded mid-section -- #6 (tunnel shot), #7 (sharp dog-leg right) and #8 (RHBH hyzer) - to the longer finishing four holes, including the 600 foot #10.
(2) Layout flow is very good with clearly marked pathways between the basket and the next hole. The only long basket-to-tee walk is between #9 and the back tee of #10.
(3) Good course for all levels as there are two sets of distances -- two tee pads - front and back - on all holes except the rather short #7 and #8.
(4) Pleasing to the eye. Thanks to regular mowing, several of the holes have a distinct fairway marked on the sides by waste-high prairie grass. It gives those holes somewhat of a feeling of being on a British Open ball golf links course. Okay, maybe that's a bit of a stretch, but like links courses, you'll want to keep your round projectile out of the tall stuff!
(5) Frequently mowed fairways (the park staff obviously take pride in their work) as mentioned above.
(6) Good signage, augmented by printed maps available at the information board by tee #1.
(7) Course is empty much of the time, especially on weekdays. While it would be great to see more usage, it's nice to have the course to yourself much of the time as this allows for a leisurely pace and ample practice putting and throwing. (See related notes in "Other Comments" about alternate layouts.)
Cons:
(1) Tee pads. While it is nice to have natural surfacing (a reddish dirt) in a natural setting, the downside is that most of the tee grounds have pot-hole type depressions. The unevenness of this driving area means you need to be careful in your striding prior to the throw release.
(2) The current pin placements make great sense, but this good quality course would be even better if there existed the option for one or two additional pin placements on some of the holes.
(3) 12 holes is better than 9, but... The course is an enjoyable length just the way it is, and the designer made good use of the land provided. But as long as there are only 12 holes, the course will likely not be considered championship caliber.
(4) Mosquitoes and ticks in the wooded holes, especially at dusk (duh). Just bring strong bug spray, and you should be fine.
Other Thoughts:
As noted in the "Pros" section, you can have the course pretty much to yourself a lot of the time. During the summer I vacation a couple of weeks in Annandale, so I have the luxury of playing on weekday mornings. If no other player is on the course, I have followed the 12-hole round by playing an alternate layout of 15 additional holes that are made up partly of following a reverse path of the course and adding a few other holes along this changed routing that target the existing baskets from various made-up tee areas. The result is that I end up with a total of 27 holes of play, a nice number for the golf purist. Rather than detail my alternate layout, I will leave it up to your imagination to create your own personalized course. That's the fun of it.
(Obviously, you should not make up different holes and play alternate routes if there are other disc golfers on the course.)
