This group of old cars are in a field a few miles south of Tallahassee, Florida. They can be found on Hwy 319 just south of Crawfordville. It took me a long time to get some info on them, but finally they are mentioned on a web page ( http://www.roadsideamerica.com/tip/15949). The page says "Ford Truck Collection
If you're heading south on Highway 319 between Crawfordville and Medart, just before the intersection of 319 and 98, you'll see a spectacular collection of old Ford trucks. They are rusty and overgrown with vines and grass, arranged in chronological order, dating from the early 1900s to the mid 1970s. They are a splendor to behold. They'll be on your right tucked along the side of the road. The trucks, placed here by Pat Harvey, have all been used on the Harvey family farm. Some were used by his grandfather and some by his father. All were left in the woods to rust when their time had passed. Mr. Harvey is completely amazed by the number of travelers who stop and take photos of this unique artistic find."
