Great bus pictures. When I was a kid, I used to drive buses very much like the one in picture #349. Detroit Diesels with 2-Speed Auto Trans. (I was good friends with a bus driver who let me drive them on quiet back streets at the end of the line).
Hibbing? I've been there...One Robert Zimmerman is from there, the the Birthplace of Greyhound lines is there, and the World's Largest Iron Ore Strip Mine, the Mahoning-Hull Rust Mine, is there. The original mine destabilized the town grounds, so they moved the town, lock, stock and barrel 1/2 mile away, but left all the pavements, front steps, foundations, street lamps, etc. Fairly eerie-looking.
