In Panama I went to the Plaza de la Idependencia of Casco Viejo because it was shown in the opening credits.
Which, when reversed look like this (thanks to Peach):
Those dresses, BTW, are the national dress of Panama: Pollera
You can buy little dolls with the Pollera dresses:
There was a greeter for our Transit of the Panama Canal and she was wearing the Pollera too!
We know from this preview that the clue is written on the dress:
This was what I was trying to get at in this post: Panama Viejo
I think that the clue to the next location is written in the design of the dress! The last five letters are: V - i - e - j - o
I can't make out the preceding letters, but Viejo is enough of a clue to make an educated guess:
The next location (or maybe even the Pit Stop) is Panama Viejo
The location of Panama Viejo is perfect for the Pit Stop. Also, the time of day that racers were there is consistent with it being the last thing they do.
When I went there, there were Panama Hat vendors in the Plaza de la Idependencia of Casco Viejo who were present on July 9th who got to see the Teams search for the clue. It was very amusing to them. I showed the pictures of the remaining 4 Teams to get identification. I even threw in some Teams we know were not there. And the hat guys said those people were not not there. So that checks out! I know I'm rambling on here so I will cut to the chase.
Tommy & Andy left the Plaza de la Idependencia 2 hours after the other three teams.The final three are: Marcus & Amani, Jeremy & Sandy, Ernie & Cindy
