Killing Fields Memorial - Phnom Penh

Out of a list of the top 10 things to do in Phnom Penh (as listed in the local city guide), we did 9. The one thing we did not do was to visit the Killing Fields memorial site outside of Phnom Penh. This the site that every single tuk tuk driver asks if you want to visit - all the time, every minute of daylight hours. Their constant touting of this was actually the most disappointing aspect of what was a nice place to visit. This constant asking worried me. Worried me in the sense that such a sacred place would be pushed so hard as a tourist destination. Imagine my horror when I learned that several years ago the site was 'sold' to a Japanese company who now run the place as a tourist attraction and presumably at a profit. Can you imagine the outrage if Auschwitz was run as a commercially operated tourist attraction??! I can understand that the Cambodian government might not be able to maintain the place properly but running the site on a commercial basis is quite upsetting apparently for many Cambodian people. I am glad I did not visit the Killing Fields site and feel that my quite contemplation at S-21 in Phnom Penh was a more appropriate response to an evil period in Cambodia's long and mostly proud history.
