A few years ago, I ended up visiting the Gettysberg site in Pennsylvania. My girlfriend at the time was in the habit of picking random directions for us to set off on road trips. The visit to Gettysburg was funny, weird, vaguely sad. Atop a hill at the battle site, a Richard Neutra building housed a large, circular painting of the last Confederate charge. After a long debate between architectural preservationists and historical re-enactors, the building has been demolished.
