From the television show from many years ago.... Dallas
There is a J R Ewing, but he does not live here.
This is SouthFork Ranch, it is not located in Dallas, it is in Parker ( would you watch a show named "Parker" )
It is not even in Dallas county, it is in nearby Collin County.
It is famous, and open for tours. Passed by this morning on the way to Denton for an Operation Lifesaver presentation. There are several trailers on the property, I think I heard something earlier about television doing a special update episode of the show.
