Unidentified Earth #70

OK! We have two identifications: UI 66 has been pegged as the Johnson Space Center in Houston, TX -- otherwise known as the location of "Mission Control". (Although I'm not sure what the object pictured there is -- some kind of antenna, maybe?) Also, UI 67 was finally pegged as Riverside, IA -- the town that has proclaimed itself the future birthplace of Captain James T. Kirk. Hooray! UI 68 is, however, still Unidentified, which strikes me as a poetic turn of events, and no one has yet shown enough pioneering spirit to peg the location of last week's UI 69. Hmmmm.

And that brings us to the new puzzler:



Where are we? Rot-13 your guesses, folks!
