Today's a Bank Holiday, but... ¶

... the Smart Panel bus departures are expecting a regular Monday service, instead of a Sunday service. Not sure if that's an issue with the Smart Panel set up, or with your data source (but I note that the County Council's online departures boards - at http://www.cambridgeshirebus.info - are correct).
Of course, not many potential users of the Smart Panel will be at work today. But the hospital's open (!), as are many of the shops. And, if this were one of the May holidays, so would most of the University.
