OK IOW faithful, what are some of the best don't miss fall open wheel races. Most tracks have a final special show to close out their season, what are some of the best out there?

Two in my area that come to mind are:
1) Port Royal Speedway's Tuscarora 50. The 51st running is this coming weekend, pays 51k to win!
2) Williams Grove National Open. The 56th running is up at the end of September and pays 56k to win.
