Thats right. A lot of them had or have property in Montana. Robert Redford was among them. One area was referred to as “Hollywood on the Yellowstone.” Ted Turner bought up enormous tracts of land (113,613 acres) in SW Montana called the Flying D ranch.
This is from Wikipedia
Ted Turner caused a stir in Montana in 2003 by providing a significant amount of funding to a project aimed at restoring a westslope cutthroat trout population to Cherry Creek and Cherry Lake. The controversy stemmed from the use of the poison antimycin to kill the abundant fish population currently living in the stream.
Recently, there has been worry that Ted Turner is systematically taking over land surrounding the Ogallala Aquifer. Ranchers in the area have consistently been outbid by Turner (and his associates).
Don’t forget Tom Brokejaw has a ranch there as well
