Pros:
The nine holes at Mize Elementary start on a field shared by football, soccer, and baseball, and then play around the school building and add a little elevation change. Tees are mostly easy to find. Surprisingly, there's a little more interesting here than most school courses.
The final four holes are pretty decent. They all have a little elevation change, decent obstructions, and varying distance. You probably won't find yourself throwing the same disc on every drive, because there's some pretty good variety on these holes.
If you add OB, the course becomes a lot more interesting. The path on holes 1-5, roads on 6-9, and a garden-ish-thing on 8. While a good player will have no trouble avoiding those hazards, it can influence decisions for newer players.
The holes are easy at the start, and slowly get harder and spicier. Even on the boring holes on the early holes, the first two are significantly shorter than the next ones. Hole 9 is labeled a par 4, though it doesn't take a whole lot of distance to reach it in one.
Cons:
The first five holes are pretty wide open and the only obstacles are the baseball backstop and a soccer goal. I think they were placed where they were intentionally, to make you throw a certain way, but they still aren't super fun to throw around.
The first five holes are pretty boring. Completely flat, only some distance, and other school activities will get in the way. Nearly any changes to these holes could make them better. A basket or tee shot from a 20-foot wide window in the woods would be wonderful, but that's not likely to happen at a school. I wish!
The woods, while they rarely come into play, are super thick and are likely to cause problems for beginners who have distance but no accuracy. The baskets should probably be 20 feet or so farther away from the woods, though that would cause more difficulties. Hole 9 has a road and guardrail in the way, which can be a decent challenge for some players but is really gimmicky. Several other holes have some danger if a shot goes awry. You're even playing next to property line on holes 6 and 9.
Even on the more difficult holes, there's still not a lot of challenge. While hole 6 is kind of a tunnel shot, there's a lot of room for error, and only hole 7 makes you want to throw a wide hyzer, though if you hit the guardian trees, you still have a putt.
Like most school courses, come at a time when there aren't any official events.
Other Thoughts:
An old school building or chapel or something is in the way on hole 6, but it actually simulates rough pretty well, and forces a much more accurate shot if you want to reach the green in one. And speaking of hole 6, if the gate by the playground is closed, you're walking and extra 1000 feet to reach the tee.
There's some safari potential on the front five if you want to lengthen the holes, and you could play some triple mandos through the field goal posts if you want.
At the end of the day, this is just another school course. This one has a little more going for it than others, and is one you can have fun playing a second time. But with the first five holes being as uninteresting as they are, it's unlikely this course is getting any better.
