"Expiry - Never"

What with the 'Bus Pass' arriving so close to our recent Christmas-trip down to London, I've actually not had a chance to use it until today - I didn't quite make it to Wick, but it got me safely to the City Centre and back ...

... I did like the fact that when I sat it on the bus card-reader, the display said: "Expiry - Never"  :-))
