As GCH mentioned, I've been down for 5 days and saw loads of different sports, most of which I haven't seen before. The handball was something I really enjoyed, but nothing could top Friday night in the Olympic Stadium, cheering on anybody British but most especially the lovely Ms Ennis.
Tickets were hard to come by, there's no denying that, but they were available. A bit of patience, a bit of pre-planning and in some cases luck allowed us to get to 7 events over 5 days.
One of my most abiding memories will be of the "Games Makers". Tens of thousands of volunteers who are the most pleasent, happy, charming people you could wish to meet. Also, once inside the venues there's no advertising anywhere. Sure there's a McDonalds (well 4 to be precise) inside the park, but there's numerous other food outlets as well.
Overall one of the greatest sporting experiences of my life. I agree that the legacy bit will take a few years to determine but at this moment in time I'm a complete believer.
