Today Kerstin drove us on the autobahn to the Dokumentationsstätte Regierungsbunker that was to be the Parliaments protection from nuclear attack drug the Cold War. It went 20km underground and was interesting. Weird having Kerstin driving us around. Then we headed into town proper of Bonn checking out the town and did a bit of shopping. The town itself is very pretty. We then went home and out to tea with the whole family - Kerstin, her two brothers, her mum and her mums parents (who speak limited English so I got to have a real go with my German. Not good but adequate so I was pleased).
