my commute home was a bit slow to start with - I was in a different part of the city, and had to get across the CBD to get to my normal route. I don't know the short-cuts and back alleys in that bit of town, so it was slow going through unusally heavy traffic.
Then a bit further on the police had closed loads of roads (around Pyrmont) - dozens of squad cars, redirected traffic, tape across the street and so on. Dont know what was occuring. They didn't seem to be stopping pedestrians or bikes though, so I was able to take my normal route, albeit a bit slower then usual. I guess this may have been part of the cause of the traffic hold-ups in the city.
All in all a rather frustrating ride home!
