Thanks Tim. Seems simple enough.
I see you are in somewher in Schleswig-Holstein. I once lived in Pinneberg from Oct. 1986 to Feb. 1987 when I was doing some landfill research at the University Hamburg-Harburg. I had to get leachate from the landfill (mulldeponie) at Rendsburg from time to time. On weekends, my wife and I would visit locations in the area, e.g. Bad Segeberg, Kiel, Lubeck, Flensburg, Heide, etc. so I know the area a bit. Too bad we never saw it in the spring/summer.
Anyway, again, thanks for the info. I am a total ABH V8 noob so you comments are very welcomed.
