No cluebox shown in this leg(all clue given in other forms)...because they don't want to spolier?
Wasn't there one after the dragonboats? And what does that thing before the roadblock count as?
I think weihen is right. We see Ernie and Cindy take a clue from one of the boatmen's 'pouch' that he's wearing. And then after the boat task, we see a clue being handed to them..
Also, regarding the roadblock clue picture, why does the logo simply say 'BLOCK'?! What happened to 'ROAD'?!
