Here's an event that wasn't on the schedule: When I came out of my hotel, and crossed the bridge to the convention hotel, I saw hundreds of people milling outside. And I figured they couldn't all be smokers. What was going on?
So see the person looking over the edge? I tapped her on the shoulder and asked what was going on. She turned, and told me the fire alarms had all gone off! So everyone scrambled (as quickly as people do when it's 8:30 in the morning and the coffee hasn't kicked in) and headed for the exits.
