Since we scheduled and extra day into our itinerary, we decided to take advantage of the down time and head to Six Flags near St Louis. We rented 2 vans and drove the 3 hours to get to the park. This Six Flags had an amusement park and a water park. We started out on the rides before the lines were too long, then in the afternoon when it was 90 degrees again, we all headed for the water park.
After a few hours of floating around, the group saddled up again and headed back to Champaign. We got back into town at about 2330 then finished packing for the early morning train.
