Cambridge's latest Park & Ride site opened last Saturday. I really needed a map of it (don't ask!) so in major drizzle and on the bleak windswept edge of the fends our intrepid hero went to map essentially a huge car park. Brought the tracks home, and what's this: parts of the car park appearing before his very eyes? Has someone added psychic thought inference to the system? No, someone else (comsomol) had exactly the same idea at pretty much the same time. A few minutes different and we'd have bumped into each other navigating round the car park. Ho hum.
