An outdoor modern art installation in the desert in southwestern New Mexico. Constructed in 1977 by Walter De Maria. It's a 1-mile by 1-kilometer rectangular grid array of 400 stainless steel poles that are meant to attract lightning. Visitors to this installation arrive in the afternoon and spend the night in a cabin that has a nice view of the show. Some nights there is a lot of lightning, and other nights there's nothing. You take your chances.
