I posted a reply on Benzworld as well. I'm surprised there aren't more meets posted.
Last year I went to an Audi TT meet in the Bear Mountain State Park area. Lots of twisty roads and scenery of the Hudson valley. We started at the Tuxedo Park train station parking lot and ended at the Stadium sports bar in Garrison, NY (point 14 on the map). We stopped at 7 (scenic overlook), 13, and 14. The other points are there just so mappoint would draw the route correctly.
Here is the route map we used.
