this is good stuff

As it is a good Congress tradition, Wednesday afternoon is off and there are no regular Congress sessions planned (other than the new public events mentioned above).

So you may want to use the free time and take advantage of the endless sights Berlin has to offer. We are in contact with the Berlin tourist office to make sure we can provide you with some great sightseeing tips as the Congress comes closer.
But we also would like to offer an organized event or two. So we're also looking into an evening boat tour, an AT Walk through Berlin, or perhaps a nice summer bicycle tour.
