The B-737-200s, which had white paint with red stripes at LAS, fly to at least two locations in Nevada, known as "Dreamland", although the two locations do not exist. I doubt that they log much actual IMC experience.
Any military pilot at Red Flag who mistakenly enters the limits of "Dreamland" (if it exists) is debriefed and leaves the exercise almost immediately for his home base.
