Web Clues:
*Friction begins to develop between Oswald and Danny.
*An AIDS march hits close to home with Danny.
Could the AIDS march happen the night of November 30th, when everyone has to wait 'till the morning for the Roadblock? If so, they would have to be in a somewhat major city for the teams, especially Oswald/Danny, to see the event. Although, they could also see the AIDS march on their way to the next task from the Roadblock (if this indeed happened on the morning of December 1st), or on the way to somewhere from something.
A possible scenario for the Roadblock: The rats are placed in a fenced area, where no Roadblocker can come in at first, and so the rats need to be on a leash. Then the rats have to sniff out a landmine type device, not exactly a land mine, and it would stay there? (I don't know exactly what the rat does when it finds a landmine... jumps up and down and points to it?
) Then I think the Roadblocker could now enter the fenced area and follow the string path made by the rat to the landmine, which is actually a clue to their next destination, only that it smells like a landmine so that the rat could sniff it out.
Thanks for your insight on Vilanculos, apskip. I removed it from the "future locations" section in the wikipedia article of
TARAS, as it's not proven yet whether the teams would really go there or not.
