Pros:
Course was pretty easy to navigate - I used a map the first time, but didn't need it on subsequent visits. Nice efficient flow to holes - I was able to play several rounds in just about an hour each. Benches and bag hooks at most tees. Two sets of tees for each hole - the shorter "A" tees (the locals called this the "rec" course) and longer "B" tees. I stayed a week in Tucson and played this course several times. It looks like tall fences have now been erected along the North side to keep discs from flying into neighboring yards. Nice shaded picnic areas. Porta-potties near the large parking lot and about halfway up the main leg up the course. Not as windy as some other area courses. Good mix of right, left, and straight-ahead approaches. Great course for beginning players - I took my in-laws and they were able to pick up the game nicely. Relatively open terrain means not many opportunities to lose discs. Practice basket near the parking lot.
Cons:
Somewhat dusty. I didn't see drinking fountains, so bringing water is a good idea. Terrain is mostly flat, and native mesquite and palo verde trees are pretty much the only obstacles. Otagonal tees were a bit short for me, but welcome nonetheless. The longer "B" tees were sometimes hard to find without a map. It seems like they were added later for longer-driving players; only a few of the "B" tees add a technical challenge in addition to extra length (10-40 yards extra, typically). Course might be considered too easy for a seasoned player. I was able to throw par games on the "A" course and 3-4 over rounds from the "B" pads (I suppose that can be a pro or con, depending on how you look at it - a good score is a nice confidence booster). It looks like the tees were re-numbered at some point, so the numbers on the posts aren't always right - the numbers painted on the pads themselves are correct, however.
Other Thoughts:
Even though I wrote a lot in the "cons" section, I really like this course. I play DG almost every day for the exercise, and this course is perfect for that: easy to navigate, efficient layout, choice of pads to fit your skill level, good parking. This is my new "regular" course now when I'm visiting family in Tucson. Make sure to print out a map with directions - the park sign is small and easy to miss the first time you visit.
