A colleague recalls a trip from Perth to Port Hedland on a overnight bus when she was doing picking up north as a student. Bus has a formidable roo-bar. During the night she was constantly woken up by annoying "pings" from the front. Early morning se got off at a stop to take a piss and witnessed the driver hosing of the roo bar. Something he did at most stops up.
