There are a few standard problems that you may expect with any park-district built course:
1) Lack of elevation changes. This shouldn't be too surprising. We're in Illinois.
2) Lack of interesting features. It feels like you are walking around a 7-segment display. Nearly the whole course can be seen from the first tee.
3) Lack of medium or long range holes. Once again, this is probably to be expected for a 9-hole course run by a park district.
Sometimes park district courses can be nice, but the following concerns have made me rate it lower than a standard park-district run course:
4) Lack of parking. The normal parking area is often blocked off during school days, and you have to park in the elementary school's lot.
5) Lack of maintenance. The tees are still dirt and there is no foul line for throwing. Replacing the sign for #9 took 8 years, and many of the signs are dirty.
6)Inconvenient location: It's far from campus, and far from interstate.
7) Lack of right doglegs. Hole 2 is really the only one.
8) Crowded. Holes 3 and 4 are often unplayable because of soccer, and hole 9 is often unplayable because of either cricket or park district football practice.
Even if the park isn't being used for other sports, the course can be crowded just from disc golf players. This is the primary course for U of I students, and players from C-U, Mahomet, and Rantoul, so it gets a lot of use. Most days, playing the back 9 (reverse tees) is impossible just because of the number of other players.
