Hmm. I'm in Chicago this July and LL was near the top of my list of day trip destinations. I don't expect it to blow my mind, but it seemed like a solid spot to bag four courses. Wondering if I should reshuffle my priorities. Looking forward to hearing the recent experiences of others!
If you are staying in Chicago, your disc golf priorities should go something like this:
1) Joliet area - The Canyons and Highland Park are an awesome combo. Plenty of other solid courses nearby.
2) Fairfield (Squaw Creek) in Round Lake - 2 Chuck Kennedy designed courses overlaid on top of one another. Gold and White.
3) Lemon Lake - 4 courses in one park. White is the easiest with many short, tightly wooded holes. Red is/was my favorite. Wooded/open, uphill/downhill/flat, long/short. There is/was a good variety of throws here. Apparently the emerald ash borer has redesigned this course since I last played. Blue and Silver/Gold are intended for more skilled players. I find Blue to be too open. Distance and playing the wind are the main challenges. Silver/Gold is challenging/frustrating for most.
4) Day Trip - Sinissippi, Quad Cities, Grey/Red/Silver Fox, etc.
5) Tier 2 Area Courses - There are now plenty of solid 18 hole courses in the Chicago suburbs other than those mentioned above. Hinsdale, Oswego, West Chicago, Streamwood, Palatine, Evergreen Park, Summit and Tinley Park contain more variety than you would think this area has to offer.
6) Nasty Niners - The suburbs are loaded with poorly designed nine hole courses. Maintenance and equipment vary, but disregard for safety is a constant. Many courses have been shoehorned into parks that don't have enough land to keep disc golf separate from other activities.
This list is basically ordered by fun/hour. The Joliet area is great, but it's also #1 due to not being as far from the city/near suburbs as some of the other options. If you are staying in the loop, really good courses will be a long car ride away.
