Two weeks ago I'd have been firmly in the "what's the point?" camp. But after a visit to the Park perimeter on Friday, and then a very lucky opportunity to attend an event on Sunday, I'd go every day to something if I had photo ID to collect tickets myself.
I'd just camp on the site and wait for last minute seat-filling opportunities (I'm hovering over one even as I type). They do seem to crop up quite regularly, and working nights means I can go to anything if I don't mind screwing my body clock up and falling asleep on trains.
This kind of behaviour, from someone with very little interest in sport generally, might tell you something about the atmosphere around this event. It is... well, addictive. The sense of occasion, the knowledge that the crowd is doing its bit to make the games successful (whether I believe we should have had them in the first place or not), and the urge to try and encourage the participants -- wherever they're from -- is a heady mixture.
However I know someone who went to handball on Sunday, which isn't at the Park, and they felt a bit let down by the experience. The event itself was ok, but unlike the Park you're out into normality too soon. At least at the Park you can wander around and soak up a bit of the ambiance and catch sights & sounds of other events. Plus there are more people all doing the same thing, with glimpses of athletes & meja celebs to spice up the day.
In short (it's a bit late for that) just go if you get the chance.
Of course it helps if you can get a ticket for something with a British participant, so you can experience being deafened by supporters, but that's not going to be possible in many cases and I definitely think that seeing any event is better than seeing no event... and then spending the rest of your life wishing you'd made the effort.
There are no shortage of experiences you can get on tap at any time of year if you have the time and money. But the Olympics on your doorstep is -- as they are so fond of saying -- a chance of a lifetime.
And they're right.
