Blue Sky Tank

This outdoor pool / tank area is used for most of the time as a studio car park. However, when required for production, the cars are moved, and 950,000 gallons of water is pumped in (at a cost of around $30,000 per fill!).
The most striking feature is the 175 feet x 75 feet sky backing which can be painted as required by the production, or left colored blue or green for CGI replacement.
The tank is positioned where the former Western Town set was located until 1979.
