When I was tracking the search terms that bring strangers to my personal site, interestingly enough, *the* most common search term was "prison pictures". I have no idea why, but I get people visiting my site from search engines with that exact search term, a couple times a week. Not "prison photos", not "pictures of prisons", not "Cambodian prisons"... It's always just "prison pictures". Anyway, here's the stuff that seems to be drawing them in. Pictures of the S-21 prison in Pnomh Penh, and the Cambodian Killing Fields, from my visit there in August 2001. It's pretty depressing stuff though, so view at your own risk.
