We can be certain that the subjects of the bus and McCandless will come up again.  And again, Hallelujah. About 5-6 years ago the Anchorage weekly free paper, PRESS, had a two full page article on why this incident hits such a nerve with Alaskans.  The author advanced the theory that disproportional numbers of Alaskans have  "dumb stuff that I could have got killed while doing but I got away with it" lists.  He suggested that many Alaskans look at Chris McCandless and see their younger and dumber selves, and don't much like what they see.

We visit battlefields like Gettysburg, Verdun and Waterloo.  Also the site of the St Valentine's Day Massacre in Chicago, Auschwitz, Dachau,  the atomic bomb Trinity test site in New Mexico, and the Old 97 wreck site near Danville, VA.  Since the site coordinates are known, the site will be visited, even if the bus is sent down Orwell's memory hole.

Perhaps some type of pedestrian bridge, even a very modest three cable job, would be appropriate.
