This weekend marks the 28th Annual Pittsburgh Vintage Grand Prix. The PVGP is America's largest vintage car race with a race course winding through Schenley Park. The Pittsburgh Harlequins are proud to announce their involvement with the PVGP this year and will be volunteering at the event from Friday July 23rd through Sunday July 25th. Funds raised from the PVGP help provide residential care, treatment and support for autistic and developmentally disabled individuals in the greater Pittsburgh area through the Autism Society of Pittsburgh and the Allegheny Valley Schools.
