A number of ACTION buses will again sport front vinyl mos as part of the annual Movember promotion...last done in 2009.
The final (?) list:
437 438 440 446 447 448 449 450 451 452
453 454 455 456 457 459 460 461 462 463
Will probably get flamed for asking, but how pray tell do these stickers help the cause?
I believe it's to try to raise awareness, in that commuters who haven't heard of Movember would ask the driver why the bus has a huge moustache on the front, the driver informs them, their interest is raised, and they might donate.
I remember as a kid seeing buses with the big red noses on the front for Red Nose Day, not sure if that operated in the same fashion though.
