Yeah, that was me! A lot of Porsche and Viper owners know me from the event down there @ Cabanis Field - those were some of the best times going down there and driving as fast as I wanted with Vipers screaming past me on the back straight and then me catching them in the twisties when they couldn't keep their power to the ground. And it only cost $20!
I stongly encourage any of you serious drivers to check with your local Porsche club as they offer these high speed driver's ed events almost monthly, provide a driving instructor until you are comfortable, and you are covered by your insurance should something happen - the events are held away from trees and curbs and I have never seen anyone crash out at the many events I have entered.
