After destroying two tires at Watkins Glen this year, I vowed to never be without a spare set of tires. I went to VIR with two tires in the trunk and two in the passenger seat, strapped in with the seat belt. This isn't workable if Lu is going with me to an event. I have a roof rack, but am interested in a hitch and getting a small tire trailer. Of course, I have more pressing needs like getting an engine built and back into the car.
