HI, Sorry to be the bearer of bad tidings for those of you thinking of using the Met line this Sat, but there is no service between Amersham and Northwood. So, don't park out at Amersham, Chalfont and Latimer, Chorleywood, Rickmansworth or Moor Park unless you are prepared to use the bus replacement service to Northwood and then get the tube on to Wembley.
Second year running this has happened. Of course it's only ordinary people in Britain who are dumb, not the highly-educated managers who make these decisions: "Oh, 85000 people at Wembley, that will make us a lot of money in fares. I know, let's have closures for the weekend and cause mass inconvenience."
In the immortal words of Richard Littlejohn: "You couldn't make it up!"
P.S. recommendations please for my annual bet on the Lance Todd Trophy winner
