I remember watching that show at the time...great episode!This was taken at the little ghost town of Nelson, Nevada a few miles south of Las Vegas. This building was used in a segment of Top Gear where Matt LeBlanc was driving around in an Octane Red Demon. I know the roads he was driving on very well now. They filmed here and then went to The Strip to launch the car down the drag strip and beat a Lambo.
