Not at the moment - but - Motoamerica will run at Barber 9/17 thru 9/19, Barber Vintage is scheduled for 10/8 thru 10/10, and American Flat Track will be in Charlotte on 10/8.
For more grass roots level racing there is the track in Jennings, Florida. In addition, for a real hoot, the Grassroots $2000 Challenge will happen in Gainesville 10/22 and 10/23. The SCCA will race at Atlanta Motor Speedway on 8/22 and 9/18. OK, OK, so the last two are not motorcycles but if you are in the Southeast and have never been to AMS, it's worth a visit. The Grassroots Challenge is just plain fun.
