Hopped the MetroNorth upstate to the Hudson Vallery area to Dia Beacon, about 80 miles north of the city. 240,000 square feet of modern art. It was an old Nabisco box-printing factory building. Only photographed part of it before security nabbed me. Missed the giant Warhol room. The whole museum was a giant meditation in white, especially the Richard Ryman area. Also passed this incredible rotting site called Bannerman’s Castle, on an island in the Hudson, seen from the train window.
