Since this has kind of become the Drive Auotx thread, when are people planning on arriving. I plan to be there at 4 on Friday and I can try to save some spots if you will let me know. I assume everyone would be good with being under the bleachers.
The Dogwood GP was a street autocross we held annually in downtown Knoxville. Our first venue was the Business Loop (it became James White Parkway) and our second venue was the South Knoxville Connector.
No cat puts you into Street Prepared. You can run any DOT approved tire (Hoosiers are awesome!). You can also run our local STM, run what you brung class. That might be your best bet since that class requires 140tw or higher.
