For this year's round of introductions we will have a grand day out with the whole group. For all members of AG1, participation is obligatory. We leave by bus in front of the institute at 9am (sharp!) and expect to be back at the institute around 8pm. On both ways, we make a short stop downtown Saarbrücken to pick up (and then drop in the evening) anybody who prefers not to come to the MPI in the morning: it's at the bus-stop in Dudweilerstrasse, between Beethovenstrasse and Lorzingstrasse right next to the parking lot (city-map link: http://sbserver2.saarbruecken.de:4680/query?GK=2572630x5456030).
