I was chatting to ITV Sport anchor Jim Rosenthal in Abu Dhabi, who summed the place up well. "They haven't just raised the bar, they've snapped it in half," he said. The Yas Marina experience was a bit like watching a race in the distant future.
One of the most enjoyable aspects, for me, were the concerts. I've already written about the Kings of Leon. Well, Aerosmith were outstanding last night. It was like rock pantomime. The Rolling Stones on acid.
After the show I popped by the paddock again to say bye to people. Most of us won't see each other again until the season starts again in Bahrain in March. Round the back of the BMW motorhome, Mario Theissen, Peter Sauber and the team's PR department were having a glass of wine, toasting the end of their alliance.
I bumped into Mario again later that evening. Red Bull and BMW were staying at the same hotel and both teams organized to have little staff parties each, around the same swimming pool. So on one side of the pool you had the winning team celebrating, and on the other the sad faces of a team which, it's ghastly to think, may well be facing extinction.
After a few drinks the parties intertwined though, and Mario created a dance floor out of nowhere and was soon jumping into the pool and mechanics threw one another in.
England cricketer Freddie Flintoff was there as a guest of Red Bull, chatting with everyone.
Sebastian Vettel was there too and stayed until the end, at 5am. He was probably quite sensible not to continue the party in one of the rooms like a few of us did. Juvenile stuff happened, and the resulting mess would probably rival that of an Aerosmith after-party.
I'd hate to see what the room looks like this morning. I left to catch my 8.30am flight and it was still going strong.
It was a suitably rock n' roll ending to an amazing season.
