 Well, it certainly is fluid and developing as we speak. And to give you an idea of the multiple rings of security, here's some of this anti-climb fencing right outside of Jersey barriers, concrete Jersey barriers. And we're very near the Pfizer forum. You see this level of security, but we're already inside the security perimeter. As I look up the hill here, that's the point where vehicles and people will be searched at the outer edges of the perimeter.
