BTMRR queue inside jokes and Hidden History (list)

The revised BTMRR queue is like the Haunted Mansion revised queue, the revised Meet Mickey, and pretty much any project these days: full of Hidden History. As the author of the book WDW Hidden History, I perk up whenever there is a tribute to an Imagineer or remnant of an old attraction mentioned. Here's what I've seen so far:

• The "pay rates" sign is posted by G. Willikers (say it out loud)
• The mining tycoon shown in a portrait is Imagineer Tony Baxter, the creator of the Big Thunder concept

• Imagineers of the Walt era (and just after) are honored on wooden signs on the Fusing Cage
• Western River Expedition, a one-time planned attraction for MK, is referenced on boxes along the path.
• The diagram map of Big Thunder includes shaft #71, in honor of the park's opening in 1971
• The diagram map officially labels the colorful cave as "Rainbow Caverns," a nod to the Disneyland ride that preceded Big Thunder at that park.
• One cage near the canaries is labeled to Rosita--answering the Tiki Room question of wondering what happened to Rosita.
• The sign announcing Hard Times Cafe makes oblique reference to the Disney movie Apple Dumpling Gang.
• The Pecos Bill sign also mentions the Mile Long Bar, a long-gone quick-service bar next to Pecos Bill (and is today the exit corridor from Country Bears).
• The Signals sign is posted by Dane Jerris (say it out loud)
