Well, it was supposed to arrive at 18:03… I was there around 17:50 and yeah, no sign of it. So unless one passed just before I got off the 61, looks like there hadn't been one for some time.
As for where I got dropped off by it… I don't recall being passed by a second one even though the LED sign at Ashgrove indicated there'd be another close behind.
The paper sign bore no resemblance to the real-world timetable being run tonight. Never a good situation.
