Survivor Tonight!

[Alex]

Was it just me or did the final immunity challenge seem designed to favor Danielle over Terry and Aras? On any balance challenge I'd give a huge edge to Terry but the setup strongly disfavored the heavier people. It is hard enough to balance on a float, much harder when your weight puts the float under water.

This was the first season of Survivor since the first one where I watched more than a few minutes so I don't know the details of the behind-the-scenes stuff. Does anybody know if the challenges are designed before the beginning of game play or do they work on them as they go along?
