Six years ago, I flew home from the Melbourne Commonwealth Games, my debut at that competition, and described it as the best sporting event I had ever worked at.
Every so often since, I have come across a picture or two and the memories kick in.
Melbourne, though, has a massive new rival in my memory banks for the greatest and, if I'm honest, the London Olympic Games 2012 beats the Australian extravaganza hands down ten times over.
What was it like in the Olympic Bubble that will burst big time over the next week? Manic, exhausting - early mornings and late nights - but, ultimately, absolutely thrilling, absorbing and inspirational.
It was also historic - day after day of sporting history made. It does not get any better than that. The superstars have been on the best form of their lives.
Usain Bolt's sprint double and, just for a bit of fun, another gold medal in a world record time in the 4x100 metres relay in the last event of the last evening in the athletics.
Also on the athletics track, Mo Farah's 10,000m and 5,000m double was incredible, as was Jess Ennis and, as I have told you before here, that men's 800m final in which every single athlete achieved a best time, whether personal or world records.
Sailor Ben Ainslie is a quadruple Olympic champion, and the equestrian - even dressage - were splashed all over the front and back pages as Britain's medal count finished third in the medal table with 29 golds, 16 silvers and 19 bronze - the highest total in a century.
Sir Chris Hoy becoming the most decorated gold medalist from Britain in history and, on a wider scale, seeing American swim legend Michael Phelps win his last gold in the 4x100m medley relay which made him the Olympic Games greatest athlete of all time.
Then there were the 'also-rans', without whom, there would be nobody for the superstars to compete against.
How to fit a fortnight of wonder into a short descriptive narrative? I'm sure I will miss out a massive highlight somewhere.
But the overall winner of these Olympics has been London, the thousands of Games Makers volunteers who have shown how great the British really are and the UK public everywhere.
Now bring on the Paralympics!
