I've also heard that Watkins Glen in Upstate NY is supposed to be one of the best tracks out there. I'd like to try and go there as well. That shouldn't be too much of a drive for you right? My buddy goes with his 911 a lot. I'll see what it takes to get a few of us Z guys in with the Porsche club.
