You push The Ram’s heavy wooden doors, ease yourself in this plush, floral-patterned booth and wonder, “Is this where Ernest Hemingway sat?” This upscale restaurant opened its doors in the lodge-studded Sun Valley Village in 1937, a couple of years before the writer started sojourning in central Idaho. On and off until his death in nearby Ketchum in 1961, Hemingway, an accomplished sportsman, fished the state’s trout streams and prowled the alpine wilderness, a rifle in hand.
