... once in a life time experience...
I haven't got much interest in sport as a spectator at the best of times, but this is what would really put me off going to the Olympics.
I watched the Tour of Britain as it came within a mile of my house a couple of years ago and it was interesting standing around with a few other cyclists waiting for the race to come past.
Sitting in an Olympic stadium surrounded by people who have never been to their local athletics track and are treating it like an Abba reunion or visit from the pope would ruin the atmosphere.
