Ticket to Ride
As the Olympics draw ever closer, I illustrate this with a picture taken of the site early on in the development (largely because I can't get out and take one now). The Olympic tickets application system is now open, and if you thought you could just click on the website and order a few tickets without any issues, you are sorely mistaken. If you are considering buying tickets (and you have until April 26th to enter the ticket lottery) I very strongly recommend you make use of Diamond Geezer's research here. Some of the issues he highlights you may well find surprising.
