This is another of Chicago's entertaining and intelligent cultural travel titles. In this one, Erin Hogan, director of public affairs at the Art Institute of Chicago, hits the road, alone, in her Volkswagon Jetta, to discover the great works of American land art in the deserts of Utah, Arizona, New Mexico and Texas. She takes in Robert Smithson's Spiral Jetty on the Great Salt Lake, Walter de Maria's Lightning Field in New Mexico, and half a dozen other landmark works. She combines excellent, clear writing on the vision and intent behind these art works, with extremely honest descriptions of her disorientation and anxiety as a woman travelling alone. It's enlightening, funny and thought provoking. It has certainly made me want to visit some of these very hard to get to art works; I can feel a trip coming on!
