I lived in London in 2010, and my Italian boss and his wife invited me out for golf one day that summer. I had hardly played in 10 years, but got the bug again that day, bad (and have it to this day).
A couple of years later we had both left the country (him to Milan, me to Moscow), but were both due to be in London in October for business trips. We made some arrangements to stay over the weekend and play out at Wentworth.
About 14 days before the trip I started checking the weather, and the long-range forecast showed a major Atlantic storm was supposed to hit that weekend. Most damned-accurate 2-week forecast I've ever seen. Three days out it was obvious the weather was going to suck. However, we had both made major arrangements for that golf weekend, and weren't going to cancel plans just because of some weather.
We ended up playing 54 holes, all three courses (East Course, The Edinburgh, and the West Course, which hosts the BMW Championship) in ok temps in the 40s, but howling winds and rain falling at about a 30* angle (almost sideways).
Had a lot of fun, but really wish it had been nice fall weather, though, instead of that which we encountered.
