The Audi Club is hosting a 2 day HPDE school at legendary VIR (their full course) on 4/16-17. Owning an Audi is not required. No special requirements for you or your car. It's two days on track with instruction in your car.
These Audi VIR schools usually sell out, but I'm told there are a still a few slots open in each run group. If you ever wanted to hit triple digit speeds legally and drive on one of the nicest road courses in the country, this is a good opportunity.
Fee is $395 and includes an event T-shirt banquet pass, and hours of track time. In addition to the track/classroom instruction, they encourage you to ride with instructors, which can be thrill rides. Some of the instructors drive some amazing vehicles. There's even one that drives a mostly stock 350Z (ahem).
If anyone is interested, I'd be happy to post the link.
