I have, the most sombre eye opening trip ever.
Walking round auschwitz itself was crazy, red brick exterior, couldnt comprehend what occured there. Seeing all the hair, still with the female plaits was just sick man.
Then ending up in the preserved gas chamber, some 600 people killed in their at a time, scratch marks on the walls, well i can honestly say that my mates and i were just silent for the rest of the day.
It was crazy.
Regarding birkenau it was the sheer scale of the place. We went when it was covered in snow. Seeing the childrens blocks with the pictures on the walls just typified the evil performed. Then seeing the actual gas chambers, even though they were destroyed was a real eye opener ya know.
i mean you can read about such things, hear accounts, but to go and experience it was a completely different experience.
