One of the carriers we operated with that summer (can't recall which) had
the callsign "Climax".

Probably in honor of a town of that name in Colorado.

Some years ago, a resident of that town wrote a letter to The Wretched
Mess News (a great little newspaper published in West Yellowstone),
"You have no idea how fatiguing it is to be in Climax 24 hours a day."
