Robin,
what a magnificent setup you have there .....
reminds me of the famous movie "Forty Thousand Horsemen" the 1940 Australian war film directed by Charles Chauvel.
The film tells the story of the Australian Light Horse which operated in the desert at the Sinai and Palestine campaign during World War I. It follows the adventures of three rowdy heroes in fighting and romance. The film culminates at the Battle of Beersheba which is reputedly "the last successful cavalry charge in history".
You have about that many horses there !!!!
Well done,
John
