fark...I'll be away in Orlando on business
You guys should go, if its anything like last year's event. This is the only one free ride and drive event where you can really flog the car without in-car supervision...BMW's UDE requires in-car instructor.
edit: reminder, they barely feed you at this event (contrast with other DEs). Plan accordingly. Also wear comfortable clothes, lines do get long for the flog test. Last event was held in fall.
