Pros:
Quail Run is a small elementary school course with a lot of creativity to go along with it. It's not a grand course, but it is certainly a fun one.
Despite being only six holes, there's a lot of fun to be had since there are technically three sets of tees. I'll focus mostly on the original/primary set, but there's a longer and a shorter layout as well. They use the same basket configuration, and only change tee locations.
Several basket placements are cool. There are the hills on holes 2 and 3, the tunnel on 1, and several tunnels on 6. Hole 5 isn't all that exciting, but at least it has a downslope behind the basket.
Those basket placements are complimented by good hole design. The hills on 2 and 3 are only challenging because of cleverly-placed trees blocking some shots. The longer tees makes those much more interesting as well.
Cons:
The good design is outweighed by bad... most everything else. A couple of holes go dangerously near roads or parking lots or backyards, the signs are just wooden (and good luck if you're playing the longer or shorter layouts), and the baskets might fall apart in the next 24 hours. Any one of those isn't a problem, but that's a lot of issues that kind of stack on top of each other.
Hole 4 is... real bad, no matter what tee you're playing from. Basket around a tree, awkward shot shape, but also not very much skill required. According to the pictures, there's a mando on the longer tee, which really makes no sense. Hole 5 is also rather boring, and its long tee barely changes the hole at all.
Most every hole could be figured out pretty easily if you have a fair amount of skill and patience. They're not that long, and while they're pretty good, they're not hard. Even on the longer layout, there are some fairly basic shot shapes.
Other Thoughts:
This place could stand to get some new signs or baskets, but I really like the design overall. And I appreciate how the additional tees produce a significantly different course without ever adding more baskets (at least, significantly different on the better holes). Some of the holes from the longer layout will play like par 4's for beginner players, but are still really fun par 3's for advanced players.
I wasn't expecting much from a six holer at an elementary school, but this one really delivered. If you are bagging courses in the area, there are some courses you might want to skip. This is not one of those.
