One of my biggest disappointments as a graduate student in Anthropology/Archaeology was not being able to get to Angkor Wat or even fly near it due to North Vietnamese anti-aircraft guns surrounding it during the war.
The red bastards stole statues and ornamental works and sold them on the world black market to get money for weapons.
That might be on my to-do list, but it's not as high as various places around the Med. Still, having been that close and not been able to have a look, that must have been frustrating.
We went there about four years ago.It’s still an impressive site.
