Arriving back from holiday to the UK in the summer of 2012, just after the Olympics had begun, I was surprised to find the city relatively quiet. Tactics to keep people from attending in large numbers had obviously worked and most Londoners appeared to be away. I wanted a party.
In the summer of 2012 the Olympics came to London. I went to a talk by TFL about how to get around while the Games were on. They probably went a little overboard in the end, but the bloke from TFL was very funny.
