About a year ago we made a trip to Vietnam. By pure coincidence it turned out that our hotel in Ho Chi Minh city was located just across the street from where the cyclo task in TAR 3 took place. I am sure most of you remember it.
The clue said to go to "2A Ton Duc Thang Street" and search for your next clue. The first team, Terry & Ian, found the clue box here without problem. They then had to drive a cyclo along a marked path to a nearby ferry terminal, take the ferry across the river and the follow the marked path to the Pit Stop. Team #2 to arrive was the wonder twins, but they had trouble locating the clue box. Eventually they followed the flags across the river. Meanwhile the last team, Flo & Zach, found the cyclos. They then met team #3 and told them where to go. In the end the wonder twins got eliminated. And those of you who followed and remember the season know what a delightful irony it was that it effectively was Flo who got the wonder twins eliminated by helping Ken & Gerard.
Anyway the area had changed quite a bit in the 9 years since the episode was filmed. I think I managed to locate where the cluebox sat. The episode capture is kind of fuzzy below, but there was a tower with some upwards facing spikes on it. I found a similar tower down the street. The left picture below was taken from our hotel room.
And pointing the camera in the other direction we see the ferry terminal:
The distance between the clue box and the ferry terminal is only a couple of hundred meters.
