A favorite stop in 2015: Ann Hamilton’s installation at SITE Sante Fe. Extinction in action: A room populated by ghostly animals, already memories. Coveting encouraged, images copied on newsprint pads, inviting rippage, each tear pushing the printed species closer to erasure. Timid at first, we got greedy (despite the glares of other gallery-goers) and tore off a zoo that now lies in piles, waiting for domestication on my wall. The guilt lingers, as it should.
