MJH2, you need to do more Wisconsin races. Whitewater was perfect for you.
Even though I thought (at the time) it was a ridiculous course; in retrospect, it was one of the most enjoyable races I've ever done. Took me 6 months to realise that though.
To be honest,most of the Chicago course aren't up to a heck of a lot. But, You have to take what you are given.
The most 'crossy course was St. Charles. Best designed was Carpentersville. Honourable mention to Jackson Park. Lansing was more fun than I expected. Northbrook had the best technical sections.
