I was at TI a few times, myself. Late '61, heading for Japan to catch VEGA AF-59, then back for ET-A school - do a google search for "K6NCG" (the ham radio club) and you'll see some pics, including mine & a membership card.
Back in '82, but they wouldn't let me on, but you could see the degradation. Parts are still sinking. Do you remember the World Fountain from the World's Fair? I used to use it for navigation from the ham station to the barracks, when the fog was thick.
