»In which I have a leaky memory

What was the name of the good-natured fellow who put up messages each day outside the San Francisco Airport Clarion Hotel? The hotel's sign faces Highway 101, and I fondly remember folksy wisdom and friendly messages from the signboard -- but can't remember the name of the man responsible, although he enjoyed some celebrity back in '98 or thereabouts. Those were the days before my carpool gave up the ghost.
