apskip, I respect your opinion fully, but in my personal opinion, it seemed as though Jeremy & Sandy were more quick than Ernie & Cindy at both the flight simulation and the typist challenge, and were only slightly slower at the map. (although editing may be deceptive as usual!)
Ernie & Cindy definitely got lucky with the whole 'The Dump' thing, but I felt as though that clue should've been expressed better, as it seemed too ambiguous compared to other 'riddles' in past seasons, such as the Quixote Studios riddle from TAR17 or the 'King of the Havanas' riddle from TAR7.
That's just my opinion - feel free to agree/disagree - but I personally felt that the clue was too ambiguous, and reading it myself, I would've gone to Jeremy & Sandy's place if I had been given a choice between the two.
