I've been meaning to add this from Lorna via peach, again it adds more evidence that there very well could be 6 teams Delhi, India via Bangkok, Thailand.
Also new info that was
pointed out by Neobie --
SA 3 legs not 4 like we originally were thinking
So
11 teams to start LA to Brazil
lose a team in Bahia, Savador 10 left
lose a team somewhere SA 9 left
lose a team La Paz, Bolivia 8 left
lose a team Auckland, NZ 7 left
lose a team in Siem Reap Cambodia 6 left ( looking at the times of the tasks on Tonle Sap , unless theres a another team way behind, I'll still "guess" that the African American couple was eliminated in Siem Reap which makes sense as well as Jason did not see a AA couple enroute to Delhi.
6 teams fly from Delhi, India via Bangkok, Thailand ..this is where we lose the sightings
We were at Angkor Wat on the 4th May when they were filming the Amazing Race. We only saw one team at Angkor for the whole time we were there which was a couple of hours. This team was both male, one with orange hair and the other with brown hair and they were at the clue box at 11.30am. (7) We also happened to see all the teams walking around Siem Reap town that evening and I recall seeing 6 teams . I would love to visit your website and I have plenty of photos I will send to your email address
....
I'm with you Chateau hes to old 
Okay so, I wanted to touch on this as well, photo evidence page 1 of this thread. What I'm trying to figure out is are there 5 or 6 teams left leaving Cambodia?

Message from Chrisrae:
*It was an African American couple. I just uploaded the only pick I have to my blog entry "cambodia's culinary delights." It's the last picture in the series. (1) photo evidence
Delhi, India via Bangkok, Thailand
* Hey everyone. Glad I could help with the Bangkok pics and info.
*As Peach posted, I can definitely identify 5 teams and (7)think there was another but can't be sure. .
*Sorry about that. Actually, I was chatting with a crew member in the customs line when they told me it was a documentary and I asked how many people there are in the "movie" and just threw 10 out there as a number and he said yeah so maybe there are only 5 teams left.
*I can definitely say that the frat guys are the guys in my second set of pics, one with a yellow headband, one with a yellow hat. They were doing pullups on the bus ride from the plane. (2) photo evidence
*The 2 girls, one blond/reddish hair, one brunette, both from Texas. (3) photo evidence
*The couple with their backs to me in the other shot is a team, they had a number on the packs. (4) Sarah & Terrance photo evidence
*Then there's the young guy with the spikey hair and his mother and (5) photo evidence
*another M/F who are together but almost positive they're not a couple. (6)NO photo evidence
*That's all I saw in terms of contestants.
*I can definitely say there was no african american team. There was one african american guy but he was a sound guy. That's it.
*What else? ummmmm, I didn't see any older couple with the group.
*We were pretty much waiting in the small Siem Reap airport together for over an hour so I got a pretty good look at everyone that was there.
1) African American pair ~Tonle Sap Lake
2) Frat guys~Delhi, India via Bangkok, Thailand
3) 2 girls from Texas~Delhi, India via Bangkok, Thailand
4) Sarah & Terrance~Delhi, India via Bangkok, Thailand
5) Mom son ~Delhi, India via Bangkok, Thailand
6) another M/F who are together but almost positive they're not a couple~Delhi, India via Bangkok, Thailand could be the guy in blue below, may or may not be paired with the blond in the cap with the green shirt?
7) I can definitely identify 5 teams and think there was another but can't be sure.
We also happened to see all the teams walking around Siem Reap town that evening and I recall seeing 6 teams
thanks for the update peach 
And some new info:
The photographer of this fellow
has sent the following info:
As far as your questions, the guy was by himself, though there was also a blond girl w a green shirt (not the one you see in the picture, she is from my group) and a white baseball hat also looking for whatever. I have no idea what exactly they were looking for, and the day I saw them was Sunday May 4, I think late AM my time. We are, I believe, 11 hours ahead of EST.
So now we have the 7 boats at Tonle Sap Lake:
The blogger said 6, but I count 7 flags there (the flags on each end are almost hidden--compare my arrows below to the original). Doesn't production often hire one extra vehicle/animal/etc. for tasks?
