The course is busy, and this can make for frustratingly long rounds at time; especially on weekends when the course is backed up with large groups.
Sometimes the busy is not just disc golfers. Unlike other disc golf parks I've played in, Veteran's often is home to folks in Renaissance or other war/medieval garb dashing about in the woods, brandishing foam swords or other weapons, and blissfully ignorant of the danger they face from flying discs. This is not frequently a problem, but happens often enough (especially on weekends) to be worth mentioning. Make sure you're errant shot doesn't take out a knight-errant.
Teepads are a mixed bag out here. Some are great, some are very mediocre, though they have improved them greatly over the years.
Signage is fair, at best. Tee signs don't have any way to specify which basket is in place (and you often can't see the baskets from the tee), and there is very little to help you navigate the course if you don't know your way around. The first time I played this course years ago, I was with my Dad and brother, and we gave up in frustration after 7 holes. The tricky walk between 7 and 8 is non-intuitive. Other places on the course aren't AS frustrating, but directional signage is cheap and is of immense importance to first-time players.
Some places on the course have amazing amounts of broken glass. Hole 8 in particular, but the course as a whole has more glass than almost any course I've played. There are places you don't want to fall and wouldn't put your knee down for balance on a tricky shot.
Course has great elevation but seldom forces a wide variety of shots. This may sound strange, but most of the trees are short enough that you can throw big hyzers and avoid most of the obstacles on the course. Some of this depends on the basket placements, but for the most part, big RHBH hyzers will solve your problems 90% of the time on this course -- which works great for some folks, but is a limitation of the course in my opinion. Forcing more variety would be nice. Visually, there are a lot of trees on the course, but once you realize you can just go higher, the course gets a LOT easier.
In my opinion, the course is limited by having only par 3 holes. Admittedly, it has several challenging par 3s (holes 1, 3L, 8, 12L, 14L, 18), but it still doesn't have the range you would hope for on a course with this much great land. Again, this is largely a factor of the low trees that you can hyzer over -- it reduces the need for strategy and placement shots. Most holes, you run a big high hyzer for the birdie and hope you can your putt. This is great fun, but not a challenge that will improve your depth as a player long-term.
Despite all the trees, this course has very little shade. Playing in summer can be a blistering experience out in the sun, and you will be bone-dry a few holes into the round. Take plenty of water, and good footwear for the rocks and cactus.
Only one set of tees are present, and only about half of the baskets have alternate placements. The course is so much fun that this doesn't really hurt replay value, but it should be mentioned.
