I stayed mostly at youth hostels during this unplanned travel time. One of the best things about staying in youth hostels is the local color you can get from other travelers. One evening I asked what I shouldn’t miss when in Munich. More than one fellow traveler told me to make sure I visited Dachau, which was not far to the north. The next morning I made my way to the Autobahn and hitchhiked north towards the infamous destination. Drivers who picked me up would ask where I was going. When I replied “Dachau”, the response was uniform; the conversation quieted to silence. In retrospect, the response shifted from awkward embarrassment to naked shame.
I had to walk the last 2 or 3 kilometers to the entrance, as it was far away from any settlement. There was no commerce or residence in the area. The day was very gray, and it was as if the whole countryside was sterile. As I approached, there was a very long border of high wire fence. Walking through the entrance I found no one in attendance. I moved in turn through all the buildings and the displays. I never found a soul the entire day, at least none that were living. The dead were extremely prominent. I recollect photos of bones covered by skin, of “scientific” experimentation by hypothermia, of long, unheated wooden buildings (still standing at the time) where the inmates slept and became infected with lice and typhus.
It wasn’t the crematoriums that impressed me. What hit me hard was the fact that the crematoriums turned out to be far too slow at processing bodies, so they were largely abandoned, in favor of firing squads and tossing bodies in large pits dug by bulldozer. Although plentiful, I'm not including any photos of this, because the images are ones that I don't want in our minds more than they already are.
