One last recommendation. I drove to Radford from San Diego because Chandler, AZ only about six hours away. My cousin lives in Sun City (about 30 miles north of Radford) so I planned to stay at his place but I should have arrived at least a full day before. Instead I arrived at my cousin's place in the evening. Being amped up from the drive and the excitement of going to Radford the next day, and also trying to sleep in unfamiliar surroundings, I got zero sleep that night. Radford starts around 8 AM and I flat out "crashed" (the energy kind, not the automotive kind) just before the afternoon drills, which include autocross and track driving. I did poorly in those drills and I wonder how much better I could have done had I been better prepared.
When you go, try to have at least one full day between your arrival and your SRT day. Two would be better. The heat will already sap a lot of your energy but running with only an hour or two of sleep will make it worse, even if you're younger than my advanced age (late 50's when I went).
