Tube life

This is where I seem to spend a large part of my day. Its a one and a half hour commute from where I live to my lovely office at Heathrow. The pic was taken at Terminal 4 before the train becomes packed with tourists.
Note to self.......remember to talk off your airport pass before getting on the train. If you wear a Heathrow pass everyone seems to think that you know all the flight details, the times of every train and how to get to Aunty Maggie who lives Glasgow.
