That fascinated me as well with this video. We have this huge motorcade, with really nice black cars, ambulance, flashing lights, etc. You can even hear the helicopters start flying closer overhead when the President gets close. Around 16 minutes or so.
I wish I spoke Spanish though. I would like to know what the little commentator girl was giggling about as the motorcade was pulling in. Also, she mention Iraq several times. GRRRRRR.
Then again, you just focused on the event even more. I had heard or read somewhere - Lord knows where - that we brought our own vehicles. Good!
