i think this may be related.
back when obama toured the intel plant i got inside info from a handfull of employees that the new intel plant that he was touring had just been completed with numerous below ground level floors intended to house heavily secretive national security related new technologies.
i recall when he arrived in hillsboro it was very unannounced and hush hush, barely any news outlets covered his visit, i spoke to many locals and none of them even had a clue he had come through.
