Saturdays are great, but you might want to check if it conflicts with a WI saturday race. Cheeseheads may be tempted to make their annual trip south if there's beer involved. Maybe make it into a WI vs IL faceoff. Points for top 3 from each state in each race. The winning state gets to donate $xxx to charity of choice, plus bragging rights. Just an idea.

Would write more but the Friday evening thirst just hit me.
