Well, its disc golf...
There are marked trees, signs up pretty high to avoid vandalism, and the objects are also marked trees - black painted lines as to not bring to much visual distraction from the rest of the park.
This course was redesigned recently, and I've heard its better than before from a few people.
The park itself is well maintained, mowed regularly, not much underbrush and hardly any stickers. There is a nice stream that comes into play a little bit, and adds some natural beauty, and the course is fairly easy to get to, with ample free parking along any of the streets that border the park.

The design is not very well thought out, as several holes play directly down walking paths and paved sidewalks in the park - I mean the "tree" mark tee is 5ft off a path, with an object tree 200 ft down the same path.
The layout is also too tightly packed into the area used, with one hole playing slightly downhill throwing directly towards the amphitheater (just a plain bad and unsafe design).
There are numerous opportunities to have am improved hole. The last designer made holes right along the roads and there are also ample opportunities to throw at cars or homes just across the street.

Fortunately, the holes are short enough that I doubt many discs go into car and front yards & there is little to no play on this course to really cause many problems.
There is a course here; but it could be so much more.
As this is an approved disc golf course, simple 'improving' the disc golf course will not require much of the red tape that goes along with getting a new course approved.
I'm in midst of talks with the powers that be to redesign the course, add baskets, tee signs, and tees.
This may take some time, but in the end we will have a safer, stronger design. One that caters to the youth in the surrounding neighborhoods, and is a perfect beginner course.
