As I mentioned, there's a parking lot on the roof of the South Station bus terminal. While most of it is enclosed by high walls that block the view, there is a catwalk near the southern end of the lot which leads to an exit stair. From that catwalk I was able to snap this aerial shot of all the people still waiting to get in. Looks like the Reich bus is gone, though. (Maybe it was just stopped at the light?)
