Headed up on the Yarra Boulevard, fresh from seeing it in a video on Rage
this morning - it must have been a while ago (about 25 years to be precise) for it to be possible for three minutes to pass in daylight hours on the Boulevard without the presence of a bicycle. Wasn't feeling especially fresh myself at the start, but gradually built into it.
There were a couple of very visible police camera installations en route (and what I think was an unmarked car towards the southern end, although they didn't seem to be doing anything). One might hope that they were looking for people dropping tacks but I doubt it.
