Richard Nagle's info rom http://www.flash.net/~rnagle7/discgolf.htm, which I'm vaguely worried will disappear so I've copied here:

Elk Grove Village, IL (Clark Park) - This is a 9 hole mach II course with concrete tees, and new tee signs in '96. There are lots of trees to contend with on this course, which makes it a challenge. It is the home course of my friends and I, so we play it a lot. There are rolling hills and a few obstacles to deal with too. Many of the holes have a dog leg left. There isn't a single dog leg right on this course. Distances range from 220 ft. - 420 ft. Some of the holes are completely blocked by trees, and some of them are completely open fairway. A nice course overall. Rating :-)

Buffalo Grove, IL (Willow Stream Park) - This is a 9 hole mach II course with dirt tees and broken or missing tee signs. Most of the holes are wide open with little difficulty to see or reach, except the 2nd hole which is right at the edge of a steep drop off (20 ft or so!). The 9th hole can be a little tricky because a public pool makes up the left edge of the fairway. I recommend this course for beginners. Rating :-o

Rockford, IL (Anna Paige Park) - This is an 18 hole mach II course with dirt tees and nice tee signs. This course is DEFINITELY a course to visit, even if it means a road trip. The part it is in is very nice. There are lots of trees and small rolling hills to make this a very challenging course. Most of the holes are extremely short, like less than 250 ft,. . .BUT. . .most of the fairways are in the shape of a letter J, and the holes are surrounded by trees on 3 sides. Very difficult to get used to. Overall a very nice course. Rating ;-)

Urbana, IL (Illini Meadows Park) - This is a 9 hole mach II course with no real tees to speak of, or tee signs for that matter. There are some trees here to make it a little challenging, but this course needs some work. Rating :-(

Libertyville, IL (Adler Park) - This is an 18 hole mach III course with dirt tees and nice tee signs. This course is challenging and unique in many ways. It has lots of trees ( a forest really ), hills, and obstacles. Part of this course is played in the woods, no kidding. It also plays through parking lots, across roads ( internal to the park ), and past playgrounds. It has the lonnnnngest hole I've ever played. I think it was about 650 ft. if I remember correctly. This is a very cool, very difficult course. Check this one out, you won't be sorry. Rating ;-)
