The Bay State Antique Auto club is hosting 2 events at the Endicott Estate in Dedham on Sept. 11. The Veteran Car show mentioned above is for cars up to 1942. On the same field they are also hosting a "Chrome, Color and Fin show for cars of the 40's and 50's. I have attended the last two years and it is a good take. It is a much smaller crowd than the July Endicott show and attracts some really interesting cars. In 2009 3 Stanley Steamers showed up, all under their own power. Other cars included Packards, Cadillacs, Cord, several Woodies, Chrysler T&C, etc.
I am in North Carolina now and unfortunately won't be able to get there this year. I hope that you Massachusetts guys can make it, it is a show that is not to be missed.
