But wait, there’s more… Surely there’s more, right?
There’s always more.
Bike light blitzes are underway in the fair city of Melbourne with all manner of good folk, falling prey to our ever vigilant Boys/Girls in Blue.
nice work putting this up
There’s more coming, promise. Slowly but. I’m waiting to hear back from TAC on a couple of fine legal points.
Don’t forget the crackdown on NO Brakes!
I really wished the fine boys/girls in blue may have some real police work to do – like get the low-life who broke into my house and stole my stuff, but I guess us bike riders are the real threat to society? surely not?
