From my LinkedIn PCA Group:

The Allegheny Region PCA invites all to a mammoth show of Porsches at the Pittsburgh Vintage Grand Prix on July 23/24.

We expect about 500 Porsches on display, double the usual number, including one of the factory prototypes of the first 911, vintage race cars, and at least one car from each of the 50 years since the ARPCA was founded. Porsche is the Marque of the Year, so pre-registered cars can have the opportunity to drive the parade lap in front of 100,000 people. More details on the full week of events at the web site. registering in advance gets two lunch tickets for each day, a dash plaque and the opportunity to win great prizes. Our goal is to raise $100,000 for the PVGP charities...help us make it and have a great weekend, while watching great vintage racing and an awesome display of cars in the International Car Show!
