I worked two summers right down the road from where the whole thing went down. When I was there was after Krakauer wrote the magazine article but before he turned it into a book so it was just a couple seasons after McCandless died. It’s probably good that they removed the bus since it had become a magnet for trouble but I am not sure what they ought to do with it now.
