Wyoming – The road from Muddy Gap to Lander invites cruise control. It's a rough expanse of sage and snow, with a seemingly perpetual side-wind. But at Sweetwater Station, the turnoff to Riverton, a small, hand-painted sign is getting drivers to apply the brakes: Old Books, Fresh Eggs for sale. Turn in and you'll meet Polly Hinds. She and her partner, Lynda German, are two of the five residents of Sweetwater Station.... and the owners of Mad Dog and the Pilgrim Booksellers.
