An intriguing task to be sure. It struck all of us as one we would like to do, but where to find a flag? Sam and Aaron work in maintenance, and have access to the shop in the back of the Atrium. One of them remembered that the boss keeps a small American flag in the shop. So the plan began....
We nonchalantly headed to the Atrium, on the pretext of putting up flyers (which I was actually doing). We bothered the people working at the desk, while Aaron checked out the keys to the shop. One at a time, sort of, we headed down the hall. I had no reason to be back there, so I had to be particularly sneaky. We encountered no resistance, and so entered the shop.
I was the first to spot the flag, and so we set ourselves up. See video for the actual capturing.
