I heard the demolition company was telling the neighboring building managers that the Green Street parking garage was going to be closed. Maybe it's a safety thing? Supposedly there is a lot of coordination going on with many of the buildings around there. I work a couple blocks away, outside the restricted area, and our entire building got a memo from management alerting us that the event was going on this weekend, and that we should avoid downtown on Sunday morning if possible. Unfortunately, we are low in our building and look the wrong direction :-( That's why I've been asking around about other ideas too...
