This is very disappointing. I've been wracking my brain since I found out, trying to think of another good lot, but nothing as enormous as Majestic Star comes to mind. I even starting looking at the overhead view on Google maps trying to find something, lol.
The only place I can think of is Illiana Speedway. They have the infield 1/4 mile oval with an X going through the center. Some pretty cool courses could be made on that. The downside is they have their own races Saturday nights, so we couldn't set up the day before. Our October dates may work, though. They don't have races in October, but do have a swap meet there on the 20th (day before our last event).
