Good stuff, Dan.
My wife and I went to Vietnam in 1996. We spent the majority of our time in and around Saigon and were some of the first outsiders taken through the Củ Chi Tunnels.
Things that stuck out for me from that trip:
1) Officially, the government still does not like us. In several places we saw billboards & signs with anti-American messages. One described us as "baby-killers."
2) Un-officially, the government welcomes Americans and treats them well.
3) The civilians seemed to love Americans and were extraordinarily hospitable and friendly.
4) They've saved EVERYTHING we left there and use it. The ships on the docks were being unloaded with our Army trucks and there were many fenced lots containing American equipment.
5) Several entrepreneurs have operations set up where you can (for a fee, of course) fire all the weapons used in the war and even ride in some of the vehicles (including tanks).
6) There are shops that sell all the gear and personal belongings taken off American POWs. It was sad to see it.
7) The infrastructure is crumbling. It's rare to come across anything built after the Americans left.
8) There were an inordinate number of maimed/crippled older men and women on the streets. You can't go anywhere without running into adults missing eyes, limbs, or sporting huge scars.
