Ranchers saddle up satellites to track herds; water-trough weigh-ins
Wall Street Journal
Murray Grey has a beef with traditional ranching methods. Each year in punishing heat, Mr. Grey has mounted a horse to round up some 5,000 cattle across a swath of the Australian Outback more than twice the size of New York City. Camping under the stars would be romantic if not for the buzzing of bush flies and the threat posed by venomous reptiles. The cattle often lost weight on the trek back to pasture after being weighed, costing Mr. Grey thousands of dollars in profit.
