Well, this is one place, I won't ever shoot again. I was advised on 2 occasions by the security due to the fact that the building is sensitive in nature. I understand their concerns, so I will not get any photos of it in the future.
Seriously? I was there for more than 15 minutes, snapping away but no one came up to stop me...hmmm. Maybe they didn't notice me or perhaps i looked like a tourist lol.
