i've done a lap of the 'ring as well (and a very very wet and foggy lap at that)....would've done a lot more if my car hadn't died at tiersgarden at the start of my second lap!
will be going back as soon as i can.
check out
www.nurburgring.org.uk lots of good stuff on that site.
i also have so many clips on my computer...if anyone wants them add me to messenger (my username is my hotmail addie) and i'll send them to you (best be on broadband tho...they're mega big).
