So all that noise last night wasn't a trial run of the motorcades for next week's visit by monkey man. This would've been just up the road, and we had the windows open last night, so that would explain why it seemed every cop car in Sydney was driving around our area. I was pretty sure I heard a gunshot, but I guess that could have been the smash.
PS: A good example of the value of the geographical tags and the RSS feeds available in the redesigned ABC news site.
