The 'Ring is great, but I'm seeing less and less mid-week days and/or evening sessions open to the public, which means it ends up being a mad weekend rush. I tend to drive it like a one way country road, where you know there's trees or walls willing to catch you out at every opportunity - has stood me in good stead so far, and I'm the only one of our small group who hasn't spun at 'Krünnchen' or 'Ex-Mühle'.
I usually drive over on Thursday evening (cheaper ferry than the Friday) and return Monday afternoon, and make a long weekend out of it.
I used to use to go quite often in the M5 (with a small group of other M5 owners), and would like to go again in the Z4.
We usually do 4-6 laps first thing in the morning (between 8am & 9am), before the 'daytrippers' arrive, and then another set in the evening, which means we tend to miss the accidents. Although one time there was a bad incident (Porsche GT3 had a leak and dropped coolant along about half the track, and denied it was him because it was air-cooled - it's not) just as we finished our fist lap at 8:15 and we didn't get back on until 1:30pm, and then it was closed for the rest of the day by 3pm.
This is what happens when a 'bit' of fluid is dropped.

One of might mates is a right liability, as he doesn't watch out for cars coming up behind and will only see them at the last minute - which of course makes him panic. He also tries to 'straight line' everything, claiming he's using the racing line, while we're all over the back of him trying to get past :thumbsdown:
