Glad you were bold enough to photo the interior Craig, had no idea what that looked like. Very very important to get this stuff documented, good job.

Couple of things: Steve Fisher has a chapter titled "History and Mystery of The Moulin Rouge" in his excellent book, When The Mob Ran Vegas, check out http://www.whenthemobranvegas.com

Googled "Pioneer Trail" as seen on the MR sign and came up with this: http://www.accessclarkcounty.com/Public_communications/pioneer.htm Unfortunatly, the .pdf brochure doesn't size the map to a readable scale but folks might find some value in the rest of the presentation.
