About 70% of Shawshank Redemption was filmed in Mansfield. We also visited the big oak tree that was at the end of the movie (located about 20min away). The "big hayfield" as mentioned in the movie is actually very small and the filed was of weeds, not hay. The remaining wall by the tree was a little less then rubble. I found out the rest of the wall was sold piece by piece on ebay...sad.
