goes with this vidcap:
The top pic is the latter half of the same challenge....lol! The big tall structure with the puzzle tables on the top is just beyond those 4 tables in the middle on the ground....couldn't fit the entire challenge in one picture...fwiw.
There are 5 separate structures at the bottom of the picture with puzzle bags at each of them. They have to navigate them all, collect their respective bags of puzzles then race to the top to finish their puzzle...
Here is Keith at his table at the top doing the puzzle...
As Tribe pointed out....
F5 RC = Simmotion
F5 IC = Tethered Challenge
F4 IC = The challenge above, the "puzzle" challenge
