On This Spot

Summary
Arthur is dismayed to find out that his friends care more about celebrity sightings than local history.

Plot
After a history lecture, Arthur prints out some images of the famous Native American Sitting Bull and a tree on the site where Sitting Bull performed in Buffalo Bill's Wild West Show. Arthur's friends are not interested, and Buster starts making a tour called the "Derek Montaigne Tour" after Arthur asks what historic events have taken place in Elwood City. Arthur and Mr. Ratburn pay a visit to Seymour Turkel (a parody of the famous writer and biologist). Turkel hands a petition to Arthur to make the same tree shown above a memorial. When Buster continues the Montaigne Tour and finds out that Montaigne never visited Elwood City, he hands the tour over to Arthur, who then changes the subject of the tour. By then, Arthur gets even more signatures on the petition.
