Hidden in the hills of Vermont is a world-class art collection open to the public. A deep breath of art, displayed inside gorgeously restored barns and buildings, nestled into a landscape surrounded by small towns and farm pastures. The current exhibit, by Danish/Icelandic artist Olafur Eliasson, is a blast of light and movement, a wild mix of art, nature and technology. A color-filled experience, in stark contrast to the frozen exterior landscape. The Waterfall installation, sited by a stream, has now been turned off for the season, but the natural waterfall a few steps away is still running beautifully. To schedule a tour, visit the Hall Art Foundation website. But hurry, they close for the season at the end of this month.
