These images are from 2012 Mopars at the Red Barns, an annual show at the Gilmore Car Museum in Hickory Corners Michigan. The Gilmore Car Museum is a true gem, one of the best Automotive museums in the country and worth a visit even if you're not a car nut.
The Mopars at the Red Barns event featured Chrysler, Dodge, Plymouth, and De Soto brand vehicles exclusively. There were some late model cars though most were from the 1960's and 1970's. Most of these images are factory stock Muscle Cars, a few of which were extremely rare low production models. The engine size is noted for those cases and also when the car has an optional engine.
