1. A taxi to Leopold Sedar Senghor International Airport (which, incidentally, easily takes the record for the number of times my passport has been checked in any passage through any airport); 2. a coach from the terminal to the plane; 3. an Iberia flight to Madrid; 4. A swish driverless train between terminals at Madrid Airport; 5. a connecting flight to London Heathrow; 6. the Heathrow Express to Paddington; 7. the Underground (Circle Line) to Kings Cross; 8. a train to Royston. As usual on a Sunday there are 'engineering works' which mean the line beyond Royston is closed. What it is about the stretch of line between Cambridge and Royston that has needed so much maintenance for twenty years and counting I doubt I will ever know; 9. a rail replacement coach to Cambridge Railway Station; and 10. a bus to Drummer Street. I omit the miles of escalators and elevators and Trav-O-Lators at the assorted airports. It feels like they would multiply the total by 30, but that is an exaggeration, I dare say.
Oh yes, did I mention I went off at short notice to Senegal on another mission to promote the gospel of Open Data? Dakar is a neat place. Ask me about it some time.
