From the minutes of the December 2013 meeting of the Balboa Park Centennial Group, obtained through a Freedom of Information Act request and a fifth of Glenlivet:
Mr. [REDACTED] noted that, during the 1935 Expo, there were tensions between the nudists and the strippers, both of whom had exhibition venues in the Park. Ms. [REDACTED] commented that "exhibitionist venues" was more like it. Mr. [REDACTED] noted that strippers and nudists always made him a little tense, too, if you know what I mean, and was told to shut up by Ms. [REDACTED]. Mr. [REDACTED] then asked if maybe the Group couldn't look into corporate sponsorship from the De Anza Springs Clothing Optional Resort and also maybe Cheetah's Strip Club in exchange for a presence at the 2015 XXXposition. Ms. [REDACTED] reminded Mr. [REDACTED] that this was the Centennial of the 1915 Expo, not the 1935, and that if he wanted to bring up his proposal again in 20 years or so, that was fine, but maybe wait until then, when she would be dead and buried. At this point, Chairman [REDACTED] noted that Mr. [REDACTED] was onto something, at least as far as the whole "then and now" thing was concerned, and asked for proposals.
"Then and now" samples may be found at the SD on the QT Almost Factual Images Gallery.
