m & m - last guests to arrive

We were invited this morning at 10.03 (!) hours to Susanne's birthday party in Zürich. We took the car, everything fine, the satnav confirmed a really good arrival time and then - the last kilometer turned out to be a traffic and parking nightmare. The place we had to go was very near Zürich Expo, where this weekend the motorbike & tuning show took place. We had no idea about it - and of course it is the audience that has to arrive there by car and motorbike. Everything blocked, no parking available and we finally arrived with 1 hour of delay.
