Anyone in the PA, MD, NOVA, NJ area who wants to go: http://horsepowering.com/specialgatherings/ . If we have a group then we'll contact Rich to get parking together. Wine tasting and parking are free but the food & beverages are catered.
There is nothing to enter as it is just a gathering of people who like cars. If you look at the pictures ( http://www.flickr.com/groups/hvhorsepower ) from the last one you'll notice all complete clean cars. They also have plenty of parking ( free ) for those without a show car but who still want to enjoy the gathering's events.
