Last week, I spent another couple of days at our track with the local PCA to participate in their annual High Performance Driving School ( Track Daze - link here ). There was great turnout with plenty of cool cars, including the new 991 GT3 RS in the picture below, which you can also see (and, more importantly, hear) pass me in the video at the end of the post at 5:55.
