The Wisconsin Marathon is in Kenosha, about an hour north of Chocago. The race is run along lake Michigan offering beautiful views. The race location was easy to find on race day. While the early miles do have some early hills, it is mostly flat. The city does seem to support this race and local businesses were happy to see all the runners come to town. Look through the race program for deals local businesses offer runners over the weekend.
Pros
The Wisconsin Marathon did a great job of updating registered runners on important details leading up to race morning
Runners had three options on where to pick up their race packet. They could go to a location in Milwaukee, or Chicago a week early or the day before the race at the race location. There was a small expo with a few vendors and races at the race location the day before.
The course is right along the lake shore for most of the race, offering a lot of great views
With good weather, this could be a great PR course
Unique finishers medals
Unique race logo allaround, used on race shirts.
13 aid stations along the marathon course and 6 on the half marathon course with water and Gatoraid. Mile 18.5 aid station has ClifShots. Aid stations also seemed to be well staffed with volunteers
Post race food options included bagels, water, cheese (of course), and bananas. Each runner Aldo had a tab on their bib for a free brat and beer. I didn't partake in the beer but the brat was fantastic.
Live band at finish line
Well marked course
If you took your bib into participating businesses in Kenosha you could get discounts or free selected items.
Mostly closed course.

Cons
Parking was a little ways away from the start/finish
Roads need re-paved in some sections
Second half of marathon there isn't much crowd support, gets pretty quiet
There are a couple of sections of gravel roads. Most of it is packed down well though.
Would like to see more food with salt (chips or something). After a marathon, I need to replenish on Salt after a marathon.
Race photos are not free and seem to be over priced.
Could do better at utilizing social media to get the word out about the race
No pacers
