It's a celebration of the past in the city of St. Clair today and Saturday with the Vintage Weekend going on at the St. Clair Boat Harbor and Riverview Plaza.  Jody Skonieczny at the St. Clair Chamber of Commerce says the vintage boats, along with the classic cars and hot rods and more will be rolling into the city and the harbor by the afternoon.  This evening is the classic car show along the boardwalk at Palmer Park with the Voodoo Doctors playing classic car tunes live.  The night also sees the All Town Reunion at Palmer Park.  Saturday sees the antique and classic boats at the St. Clair Boat Harbor.  That's along with the Tin Can Tourists, which is an all make and model vintage trailer and motor coach club.  Also, Riverview Plaza's central courtyard and hallways will be converted into an antique flea market.
