This morning we had our tour of Auschwitz. Only 19 of us chose to go. Auschwitz is about 70 km from Krakow. We visited the museum which is at the main camp ("Auschwitz 1") and then briefly drove by the camp where most of the killing was done ("Auschwitz 2 - Birkenau") as most of what's there is a reconstruction; the Nazis destroyed most of the evidence before the Russians liberated the camp.
It's a sad and sobering experience. I think pretty much everyone cried at least a little, at one point or another. The section that got to me the most was in the area where they displayed personal effects that had been taken from the victims -- there was a display of thousands of children's shoes. It was just too much.
After our visit we returned to Krakow and we have the rest of the day free. Tomorrow we have a long drive to Prague.
