I took this photo while walking around the perimeter of Auschwitz II-Birkenau in Oświęcim, Poland. The barracks in the distance are to the left of the barracks where Edith, Margot, and Anne Frank stayed, specifically sector BIb of the women's camp.
After Birkenau, I traveled through Kraków and stopped to pick up some food and drinks for the long ride ahead, huddled up in the rail car.
