I know it is a bit early, but I love this event and Porsche is the Marque of the year at the event. I usually take my Audi, but I might take my Beck Speedster this year and put it in the American car show. I just like to park it in the show to walk around. Here is information on the event. It has been mentioned here in year's past, but I figured I would see if there is any interest. I highly recommend going and entering any car really.
www.pvgp.org is the link. I couldn't find a way to just post a link.
