Yea that's the one. Wish I could have done it or the Arc for free with Amazing Race Asia. Darn! hahahaha.
And yes I saw the team parking at Kawarau bungy site and running into the building as I was leaving the area. This was the campervan that there were driving around with in New Zealand if I'm not mistaken?
But anyway I didn't get to see their faces, but was a male+female team I think. Either one was wearing a neon green jacket if my memory doesn't fail me.
Allan Wu with the winner from Season 1 who then joined the production team. (Was it Joe Jer or Zabrina i think?), and the next one was with the production team. Sorry for the blur photos as I approached them and they said we couldn't take any photos, so i zoomed to the max from a far far away place where they couldn't see me lol. Then again the photos turned out to be quite useless, sigh.
Oh yes, now that you've reminded me, Gibbstown is the super famous vineyard for the South Island in NZ that was mentioned in my tour. Passed by it but didn't see anything over there. Now that name rings a bell haha
