Quote from Forbes:
The 10-bedroom Blixseth mansion will sit on 160 acres and come with a private gondola-like chairlift that will whisk residents up to the Yellowstone Club’s private ski slopes. There will also be an indoor/outdoor swimming pool separated by a glass wall that can slide away on warm summer days, as well as a home movie theater--practically a standard feature in super high-end homes. The home will come furnished.
“When someone writes that kind of check, they don’t want to have to worry about knives, forks and spoons,” says Blixseth. “The wine cellar should be stocked.”
